So you're planning a Key West trip in November? Smart move. After dealing with sticky summers here for years, I can confirm November's the sweet spot. Seriously, last November I walked from Mallory Square to Higgs Beach without turning into a puddle of sweat - miracle territory for Florida. Let's break down exactly what to expect from november weather in key west fl so you can pack right and dodge surprises.
November means transition time down here. Humidity drops like a rock after October's rains. Mornings might start at 70°F (21°C) and peak around 80°F (27°C) by afternoon. Water temps hover near 80°F too - still bathwater-warm but not hot-tub intense like August.
Key West November Weather By the Numbers
Don't just take my word for it. Here's what historical data says about november weather in key west florida:
| Weather Metric | Average | Range | Notes |
|---|---|---|---|
| High Temperature | 80°F (27°C) | 76-84°F (24-29°C) | Peak heat around 2 PM |
| Low Temperature | 71°F (22°C) | 67-75°F (19-24°C) | Coolest just before sunrise |
| Sea Temperature | 79°F (26°C) | 77-81°F (25-27°C) | Ideal for swimming/snorkeling |
| Rainfall | 2.5 inches | 1-5 inches | About 8 rainy days monthly |
| Humidity | 75% | 65-85% | Drops significantly from summer |
| Sunshine Hours | 8 hours/day | 6-10 hours | UV index still high (6-7) |
That humidity drop changes everything. November mornings feel crisp compared to summer's soup-air. But don't get cocky - sunburn happens faster than you think. Got scorched waiting for sunset at Mallory Square last year despite "mild" temps.
Pro Tip:
Pack layers. Mornings often feel cool enough for light sweatshirts (especially on boats), but you'll roast by noon. I keep a packable windbreaker in my day bag constantly.
What Actually Feels Different in November
Beyond numbers, november weather in key west fl brings tangible shifts:
- Rain patterns change: Instead of daily afternoon thunderstorms, you get quick-moving fronts. Lasted 45 minutes during my kayak tour last November - guide didn't even pause.
- Wind picks up: Northeast trade winds arrive, averaging 10-15 mph. Great for sailors, annoying for umbrella drinks. Saw more than one cocktail fly off oceanfront tables.
- Sun angle lowers: Golden hour starts around 4:30 PM in late November. Sunset celebrations get magical lighting without the brutal heat.
- Crowds thin out: Between hurricane season paranoia and pre-holiday lull, you'll find breathing room. Walked into Blue Heaven without waiting? Unthinkable in March.
Water Activities: Still Worth It?
Absolutely. Ocean temps around 79°F mean comfortable swimming through month's end. Did a November snorkel trip to Looe Key - visibility exceeded 60 feet with no summer plankton bloom. Just note:
Dry Tortugas Ferry
Why November rocks: Calmer seas mean less chance of cancellation (still happens though - ask me about my 2022 disappointment).
Booking tip: Reserve 3+ months out despite "off-season"
Cost: $190 adult round-trip
Fishing Charters
November bonus: Sailfish migration peaks! Landed my first off Cudjoe Key last fall.
Watch for: Windy days make Gulf waters choppy
Cost range: $600-$1200 for 4-6 hour private charters
November Packing List: What You'll Actually Use
Forget generic "tropical vacation" lists. Based on messy experience packing wrong:
- Must-haves:
- SPF 50+ sunscreen (I prefer mineral sticks for faces - less dripping)
- Lightweight long-sleeve rash guard (sun protection + wind buffer)
- Collapsible water bottle (hydration stations throughout Old Town)
- Waterproof phone case (sudden rain squalls + boat splashes)
- Nice-to-haves:
- Compact umbrella (smaller than rain jackets in humidity)
- Reef-safe sunscreen if snorkeling (required at state parks)
- Aloe vera gel (trust me)
- Leave home:
- Heavy jackets (saw a tourist lugging parka once - don't be that person)
- Formal shoes (sand rules everywhere)
- Hairdryers (humidity wins)
Confession: I stopped packing jeans years ago. Even November nights feel too muggy for denim. Linen or quick-dry pants work better when you hop between air-conditioned bars and humid sidewalks.
November Event Wildcards
Local happenings that impact your november weather in key west fl experience:
- Veterans Day (Nov 11): Parades draw crowds but minimal weather impact. Streets get packed fast though.
- Thanksgiving Week: Busiest November period. Book restaurants weeks ahead. Weather usually holds though - ate turkey outdoors at Louie's Backyard last year.
- Boat Race Week (mid-Nov): Offshore powerboats roar past. Fun spectacle but avoid waterfront hotels if noise-sensitive.
Heads Up:
Thanksgiving marks the start of "season." Prices jump and crowds surge after Nov 20. For better deals and thinner crowds, target early November.
When November Weather Goes Sideways
It's still Florida. Things happen. Based on 15 years here:
- Cold fronts: About 1-2 per November. Temperatures can dip to 65°F (18°C) for a day. Locals break out parkas (seriously).
- Nor'easters: Rare but brutal. Got trapped for 3 rainy days in 2018. Always have backup indoor plans.
- Remnant storms: Late hurricanes occasionally graze us. Monitor forecasts 10 days out.
If things turn soggy, pivot to:
- Harry S. Truman Little White House (adults $25, open 9AM-4:30PM)
- Key West First Legal Rum Distillery (tours $19, tastings included)
- Fort Zachary Taylor State Park (indoor museum + covered picnic areas)
November vs Other Months: Why It Shines
Key West november weather stacks up surprisingly well:
| Month | Avg High | Rain Days | Crowd Level | Best For |
|---|---|---|---|---|
| September | 89°F (32°C) | 16 | Low | Budget travelers |
| October | 85°F (29°C) | 12 | Medium | Festival lovers |
| November | 80°F (27°C) | 8 | Medium-Low | Comfort explorers |
| December | 77°F (25°C) | 6 | High | Holiday seekers |
Honestly? November beats December despite cooler temps. Fewer Christmas tourists mean you can actually move down Duval Street.
