Noter fra rejsende om Key West i december
Noter fra Everglades National Park i nærheden (128 km væk)
Key West har ikke sine egne noter for december endnu — disse handler om Everglades National Park, tæt nok på til at dele sæsonen.
Everglades-forum threads on the best time of year consistently point to December through March, and posters call December specifically the start of the reliably dry-season stretch, comfortable, breezy conditions replacing summer's oppressive heat and near-daily storms. Regulars describe wildlife viewing as genuinely stronger this time of year, lower water levels concentrating alligators, crocodiles and wading birds around the remaining pools rather than scattering them across the flooded high-water landscape. Mosquito pressure is called dramatically lower than the warmer months, a real quality-of-life difference for anyone hiking the boardwalk trails. Posters name Anhinga Trail and Shark Valley as the standout December picks for reliable, close-up wildlife sightings. Regulars call the crisp light this month a genuine bonus for photography. The record: 26.2C days feeling like 27C, 17.3C nights, a low 76 percent humidity and 10.5 hours of daylight.

Regulars are consistent this counts as genuinely pleasant overall, warm and sunny with little rain chance the norm, though several cold fronts each winter bring a handful of windy, noticeably chillier days, temperatures dropping 10-15 degrees below the run of the month. Our row backs that mild, still-dry read, 23.9C over 17.9C nights, with 46.9mm of rain across 5.2 days and a real 30.9 kph wind. Regulars are consistent this is high season here, prices climbing accordingly, jeans and a light sweater the standard packing advice for evenings and any cold-front days rather than a full coat. The sea sits at a swimmable 24.6C despite the water reading cooler than the air on paper. The record: humidity 77 percent, 9 hours of sun and AQI 45.
Regulars call this a transitional month rather than a settled one - awesome, un-oppressive weather in some years, hot and humid in others, with the one consistent change being winter's wind finally easing off, which makes it a favoured month for getting out on the water. Our row leans toward the warmer read, 30.2C reading as 34C at 77.1 percent humidity, over 24.1C nights, with 103.6mm of rain across 6.9 days. Regulars are specific about the calendar that follows: real humidity builds from late May, June brings the heat and the start of hurricane season in earnest, so May is the last easy month before both arrive. The sea stays calm and warm at 28.6C, good for fishing and snorkelling either way. The record: 11.9 hours of sun, a 25.7 kph wind and AQI 44.
Key West-forum threads on November weather call it, along with October, one of the genuinely nice stretches of the year - warm days, cool nights, humidity down from summer's peak, closer in feel to spring than to the hurricane-season months just before it. Showers do still happen, but posters say it's rare for one to be more than something passing through rather than a washed-out day, and some stretches go by without a cloud in sight. The end of the month can turn unpredictable - a late-season storm or a couple of chillier days are possible - but the average still comes out ahead of what preceded it. High-season lodging rates don't kick in until mid-December, making early November good value too, alongside a couple of specific events in the first half of the month. The record: 27.3C days feeling like 29C, 21.9C nights, 68mm across 4.9 days, a 27.4C sea, 76 percent humidity, wind averaging over 29 km/h and 9.5 hours of sun.
February in Key West is sunny and mostly dry - our row gives 41.4mm across 3.7 days - with an average high near 76F and a low near 66F, and most visitors getting 70s-to-80s days and cool nights. The word regulars repeat is windy. Our row's 28.6 kph is the strongest wind of the Key West year, and the consequences they list are the water ones: it is not a great month for water activities, and the wind is enough to make the ferry a poor bet. A cold front can also drop a couple of days into low-60s highs and low-50s nights, which is why the packing advice is shorts plus one sweatshirt. This is also peak season. The record: 26C days, 19.9C nights, 10.1 hours of sun and a 25.3C sea.
