How do Key West and Seattle compare?
The window for both is narrow but opposite — Key West is December through April before hurricane season and 95°F summer humidity; Seattle is June through September before the gray rain settles in. Key West is the squeak of flip-flops on Duval Street at 4 PM, Hemingway's six-toed cats at the Whitehead Street house, key lime pie at Kermit's still warm from the oven, and the nightly sunset celebration on Mallory Square with conch-shell hornblowers. Seattle is the smell of fresh salmon being thrown across Pike Place Market, an espresso at the original Starbucks at Pike Place (cash-only, mermaid logo unfiltered), the Seattle Center monorail to the Space Needle, and the 90-minute ferry ride to Bainbridge Island past Mount Rainier.
Mid-range nights run $350 in Key West against $290 in Seattle — Key West has the highest hotel prices in Florida because it's a tiny island with finite supply. A conch-fritter-and-margarita dinner at Half Shell Raw Bar is $40; a Pike Place Chowder lunch is $15. Both score 4 on food. Key West wins on walkability (5 vs 4 — the entire island is 4 miles by 1 mile) and nightlife (5 vs 3 — Duval Street vs Capitol Hill). Seattle wins decisively on nature access (5 vs 4) — Mount Rainier and Olympic National Park are genuine wilderness, both within a 2-hour drive.
Pair them on opposite-season trips, never the same week. Key West rewards a 3-night car-free vacation; Seattle is a launchpad for a 7-day Pacific Northwest road trip. Pick Key West for sunset-celebration nights and Hemingway-cat afternoons. Pick Seattle for Pike Place mornings and Mount Rainier weekends.

🛡️ Safety
Key West
Key West is generally a safe small city for tourists. Old Town is well-policed and busy; the main risks are alcohol-related incidents (Duval Street late-night), aggressive scooter rentals on busy streets, sun exposure, and the seasonal hurricane risk. Petty theft from rental scooters and unattended beach belongings does occur. The island's relaxed, party-oriented culture means common sense is your best safety tool.
Seattle
Seattle is generally safe for visitors, with low rates of violent crime in tourist areas. Property crime (car break-ins, package theft, bike theft) is common. Homelessness is visible in parts of downtown, Pioneer Square, and SoDo. Avoid empty downtown streets and Third Avenue late at night.
🌤️ Weather
Key West
Key West has a tropical savanna climate moderated by surrounding water — temperatures stay narrowly between 18°C (winter low) and 32°C (summer high) all year. There is a wet season (May–October, with afternoon thunderstorms and hurricane risk) and a dry season (November–April, which is also peak tourist season). Hurricane risk is real — Hurricane Irma in 2017 caused major damage to the Lower Keys.
Seattle
Seattle has a temperate oceanic climate — mild year-round with a pronounced wet season from October through April. Summers are dry, sunny, and cool. The famous rain is usually a fine drizzle ("Seattle mist") rather than downpours. Snow at sea level is rare.
🚇 Getting Around
Key West
Key West Old Town is small (about 2 miles by 4 miles total island) and the historic centre is almost entirely walkable. Bicycles are the favourite local transport — flat terrain, dedicated bike lanes, and bike racks everywhere. The Duval Loop bus is free; Uber and Lyft operate but are more expensive than in Miami. Renting a car for the week is unnecessary unless you're visiting other Keys; parking in Old Town is scarce and expensive ($4-8/hour, $25/day in city lots).
Walkability: Old Town is one of the most walkable small-city centres in America — flat, compact, shaded by tropical canopy, and full of architectural detail. The full Duval Street walk takes 25 minutes end to end. Bicycles extend the comfortable range to the entire island.
Seattle
Seattle transit is run by Sound Transit (regional) and King County Metro (buses, streetcar, water taxi). Light rail, buses, streetcars, and Washington State Ferries form a useful network. An ORCA card works across all systems. Driving downtown is painful — traffic is consistently ranked among America's worst.
Walkability: Downtown, Pike Place Market, Pioneer Square, and Seattle Center are all walkable — but prepare for steep hills. Capitol Hill, Ballard, and Fremont are each walkable neighborhoods, but you'll want transit between them. The Link light rail plus walking will cover most of what you want to see.
