Monterey in December transforms into something completely different from the California coast you might be imagining.
I’m talking grey skies, unpredictable rain, and temperatures that’ll have you questioning whether you packed the right clothes.
But here’s the thing most travel guides won’t tell you: December might actually be the best time to experience the real Monterey, crowds be damned.
The Weather Reality Check You Actually Need
Let me cut through the rubbish you’ll find on every other travel site.
December in Monterey isn’t freezing, but it’s not exactly beach weather either.
You’re looking at average highs around 59-60°F (15°C) and lows that drop to 48°F (9°C).
The real kicker? December is officially the coldest month in Monterey, tied only with February for that dubious honour.
Here’s what the actual data shows:
- Temperature rarely exceeds 68°F or drops below 53°F during the day
- You’ve got a 27% chance of rain on any given day
- Expect about 5 rainy days throughout the month
- Total precipitation hits 93.8mm, making it the wettest month of the year
The sun rises around 7:10 AM and sets by 4:53 PM.
That’s barely 9.7 hours of daylight.
On December 17th, you’ll experience the shortest day of the entire year.
Why This Isn’t Your Typical California Winter
Coastal California weather operates on a completely different rulebook than the rest of the state.
Whilst inland areas like Carmel Valley might see highs in the low to mid-60s, the coast stays stubbornly cool.
Light breezes pick up throughout the day, and whilst they’re not strong enough to ruin your plans, they add a crisp edge to the already moderate temperatures.
I remember standing at Lovers Point Beach one December morning, watching the waves crash whilst everyone around me was bundled up like we were in Scotland rather than California.
The locals seemed unfazed, walking their dogs in light jackets whilst I stood there in three layers wondering if I’d completely misjudged this trip.
A woman next to me, clearly a regular, laughed and said, “First December here?”
She explained that the beauty of Monterey in winter isn’t despite the weather—it’s because of it.
The reality is this: You need to pack like you’re visiting a temperamental British seaside town, not sunny California.
The Packing List That’ll Save Your Trip
Forget what you think you know about California weather.
December in Monterey demands a completely different approach.
Your essential packing list:
- Layered clothing that you can add or remove throughout the day
- Waterproof jacket (non-negotiable, not optional)
- Comfortable waterproof walking shoes because wet cobblestones and slippery paths are real
- Light sweaters and long-sleeve shirts for the bulk of your wardrobe
- One warm jumper for evening activities
- Scarf and light gloves if you’re particularly sensitive to cold
The layering strategy isn’t just smart—it’s essential.
Morning temperatures might feel mild, then fog rolls in by midday, and suddenly you’re reaching for that extra layer.
By afternoon, if the sun breaks through, you’ll be peeling layers off again.
Don’t make the mistake of packing just t-shirts and shorts because “it’s California.”
You’ll spend your entire trip shivering and regretting every decision.
Breaking Down the Month: What to Expect Week by Week
December isn’t one consistent weather pattern—it shifts as the month progresses.
Early December (1st-10th):
You’ll see highs ranging from 57-62°F with lows between 41-49°F.
This is typically the milder portion of the month, though “milder” is relative.
Mid-Month (11th-20th):
Temperatures cool down slightly.
Average highs drop to 56.3°F whilst lows hover around 48.2°F.
This is when you’re most likely to encounter those grey, drizzly days that characterise Monterey’s winter.
Late December (21st-31st):
Things warm up marginally again, with highs returning to the 59-62°F range.
However, weather variability increases as winter properly settles in.
The unpredictability is the real challenge here.
You might wake up to gorgeous sunshine and crystal-clear views of the bay, then find yourself caught in drizzle by lunchtime.
Or you could have three consecutive grey days followed by the most spectacular coastal sunset you’ve ever witnessed.
The UV Index Surprise Nobody Mentions
Here’s something that catches people completely off guard: even in December, even with cloud cover, you still need sun protection.
The moderate UV index means that extended time outdoors requires SPF 30+ sunscreen.
This isn’t about vanity—it’s about not spending your holiday looking like a lobster.
Why UV protection matters in December:
- Cloud cover doesn’t block UV rays as effectively as people think
- Reflection off the water amplifies UV exposure
- You’ll likely spend more time outdoors than you realise
UV-blocking sunglasses aren’t just recommended—they’re essential if you’re planning any time near the water or on the beaches.
The combination of winter sun, reflective surfaces, and potentially longer outdoor exposure (because the weather feels mild) creates the perfect storm for unexpected sunburn.
When “Unpredictable” Becomes the Only Reliable Forecast
Weather unpredictability in Monterey during December isn’t a bug—it’s a feature.
You’ll find a frustrating mix of cold and rainy days punctuated by occasional sunny, mild periods that make you question whether you over-packed.
The variability changes year to year too.
Some Decembers are relatively dry with more sunny days.
Others feel like one long, grey drizzle punctuated by brief moments of clarity.
This is why flexibility isn’t just helpful—it’s mandatory.
Your planning strategy should include:
- Booking activities that work in multiple weather conditions
- Having indoor backup plans for every outdoor activity
- Accepting that some days will simply be better for cosy cafés than coastal walks
- Embracing the moody, dramatic weather as part of the experience
The locals will tell you the same thing: if you wait for perfect weather in Monterey in December, you’ll miss out on everything that makes this month special.
The dramatic skies, the crashing waves during storms, the fog rolling in over Cannery Row—these aren’t obstacles to your trip.
They’re the main attraction.
How Monterey’s December Compares to the Rest of the Year
Context matters when you’re planning a December visit.
Monterey in December is drastically different from Monterey in November, when average highs reach 72°F and the sun seems permanently stuck in the sky.
December is officially the wettest month of the year whilst September is the driest.
That’s not a minor difference—it’s a complete climate shift.
But here’s what makes December special: February matches December for cold temperatures, but December has something February doesn’t.
Holiday atmosphere.
Fewer crowds than summer.
And prices that don’t make you want to remortgage your house.
The trade-off between weather and experience becomes incredibly favourable if you’re the type of traveller who values authenticity over guaranteed sunshine.
You’ll see Monterey as the locals experience it, not as a carefully curated tourist destination dressed up for peak season.
The seafood restaurants aren’t packed to bursting.
The Monterey Bay Aquarium doesn’t require booking weeks in advance.
You can actually walk along the coastal recreation trail without dodging selfie sticks every three metres.
The Daylight Challenge You Need to Plan Around
Those 9.7 hours of daylight aren’t just a statistic—they fundamentally change how you need to structure your days.
With sunset hitting at 4:53 PM, that gorgeous coastal drive you planned for late afternoon?
You’ll be doing it in darkness unless you adjust your schedule.
Smart daylight strategies:
- Schedule outdoor activities and photo opportunities for mid-morning through early afternoon
- Plan indoor activities (aquarium visits, wine tasting, museums) for late afternoon and evening
- Book dinner reservations for after dark when you’d be indoors anyway
- Use early mornings for coastal walks when the light is softest
The shortened days actually create some magical lighting conditions.
The low winter sun casts long shadows and creates that golden-hour glow for a larger portion of the day.
Photographers and Instagram enthusiasts will find the lighting conditions absolutely spectacular, even if they have less time to work with.
Understanding the rhythm of December’s light patterns transforms your trip from potentially frustrating to strategically brilliant.

What the Crowds (Or Lack Thereof) Mean for Your Experience
The absence of summer tourists changes everything about how you experience Monterey in December.
I’m not exaggerating when I say you’ll have world-famous attractions practically to yourself.
The Monterey Bay Aquarium on a December weekday feels like a private viewing.
You can stand in front of the kelp forest exhibit for as long as you want without someone’s elbow in your ribs or a child screaming about finding Nemo.
The jellyfish gallery becomes meditative rather than claustrophobic.
Here’s what the reduced crowds actually mean:
- Restaurant reservations available with 24-48 hours notice instead of weeks
- Parking spots along Cannery Row that don’t require circling for 30 minutes
- Hotel rates that are 30-50% lower than summer peaks
- Staff at attractions who actually have time to answer your questions
- Authentic interactions with locals who aren’t exhausted from tourist season
I walked into a restaurant on Fisherman’s Wharf one December evening without a reservation.
The host looked genuinely pleased to see us rather than hassled.
He sat us at a window table overlooking the harbour—the kind of spot that would be impossible to get in July without booking months ahead.
The server took time to explain which fish had been caught that morning and recommended a local wine that wasn’t on the menu.
The Hidden Cost Savings Nobody Calculates
Beyond the obvious hotel discounts, December in Monterey offers cost advantages that compound throughout your trip.
The real savings breakdown:
- Accommodation: 30-50% lower than summer rates, sometimes more for midweek stays
- Rental cars: Significantly cheaper with better vehicle selection
- Tours and activities: Off-season discounts of 10-25% common
- Dining: Special winter menus and prix-fixe options unavailable in summer
- Wine tasting: Reduced or waived tasting fees at many Carmel Valley wineries
But here’s the savings category people never consider: your time.
When you’re not spending 45 minutes looking for parking, 30 minutes waiting for a table, and another 20 minutes queuing for attractions, you’re effectively getting more value from each day.
Time saved is money earned, especially when you’re paying for accommodation by the night.
A three-day December trip might pack in more actual experiences than a five-day summer visit simply because you’re not constantly battling crowds and logistics.
Activities That Actually Improve in December Weather
Contrary to what you might think, some of Monterey’s best experiences are enhanced by December conditions.
Whale watching becomes spectacular in December.
Grey whales migrate along the coast from December through April, and the cooler weather means calmer seas and better viewing conditions.
The tours run rain or shine, and you’ll see fewer boats crowding the whales.
I took a whale watching tour on a crisp December morning when the fog had just lifted…
Point Lobos State Natural Reserve transforms in winter.
The dramatic weather creates those moody, windswept coastal scenes that look like they belong in a BBC nature documentary.
The 17-Mile Drive becomes otherworldly.
When fog rolls across the Lone Cypress and waves crash against the rocks below, the experience surpasses any sunny-day photo.
Wine tasting in Carmel Valley works better in December.
The tasting rooms are quieter, the staff has time for actual conversations about the wines, and the cooler weather makes the valley’s microclimate feel more like traditional wine country.
Indoor Alternatives That Justify the Trip By Themselves
The Monterey Bay Aquarium deserves multiple visits.
With reduced crowds, you can actually experience it properly rather than just ticking it off your list.
Cannery Row’s history comes alive indoors.
The Monterey Museum of Art houses an impressive collection of California art and photography.
Historic downtown Monterey offers walking tours through Colton Hall, the Custom House, and other preserved buildings from California’s early statehood period.
Shopping along Alvarado Street and in Carmel-by-the-Sea becomes pleasant rather than overwhelming.
The Food Scene When Chefs Actually Have Time to Cook
The seafood tastes better in winter months.
Dungeness crab season runs from November through June, with December offering some of the finest specimens.
Winter restaurant specials rival anything you’d find in major food cities.
The farmers markets continue year-round with winter produce that California does brilliantly.
What the Locals Actually Do in December
Morning coffee walks along the recreation trail become a ritual.
Weekend trips to Big Sur happen year-round, but locals prefer winter months.
Holiday events in downtown Monterey and Carmel bring out the community.
Locals hit the wineries midweek when tasting rooms are nearly empty.
Evening bonfires at Carmel Beach happen when weather permits.
The Photography Opportunities That Only Exist in Winter
The dramatic skies create natural filters that photographers spend thousands on equipment to replicate.
Fog becomes your creative partner rather than an obstacle.
Lower crowds mean unobstructed shots of iconic locations.
Wildlife photography improves dramatically because animals aren’t constantly disturbed by human traffic.
The golden hour extends longer due to the lower angle of winter sun.
Storm photography attracts professionals who specifically visit Monterey in winter.
Transportation and Getting Around in December Conditions
Driving conditions require more attention than during dry summer months.
Public transportation actually works better in December.
Walking remains the best way to experience downtown Monterey and Cannery Row, but waterproof shoes become non-negotiable.
Ride-sharing services (Uber, Lyft) have better availability in December.
Parking becomes almost easy compared to summer impossibility.
One critical tip: If you’re planning to drive to Big Sur or down Highway 1, check CalTrans road conditions before you go.
The Events and Holidays That Define December in Monterey
Christmas in the Adobes transforms historic downtown Monterey into a living history celebration.
Carmel’s holiday celebrations lean into the town’s fairy-tale aesthetic.
Monterey Bay’s Holiday Lights celebration at the aquarium offers after-hours holiday-themed tours.
First Night Monterey on New Year’s Eve provides alcohol-free celebrations with performances, activities, and fireworks over the bay.
Wine and food events pop up throughout December.
Why December Might Actually Be the Perfect Time for Your First Visit
Here’s the counterintuitive truth: December’s challenges make it ideal for first-time visitors who want to actually understand Monterey rather than just photograph it.
The dramatic weather creates memories that sunny-day visits simply cannot match.
