Weather in Key West in November

Prime time. November is about as good as Key West gets. Highs average 25.6 °C, lows 24.4 °C, and rain falls on 8 days — nothing in the month is working against you.

November ranks 6 of 12 in Key West: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 8 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average November reaches 30 °C; the day barely swings — 1.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 28.9 °C and the coldest night fell to 17.9 °C, and the wettest single day dropped 73 mm — roughly 149% of the month's rain in one day.

This is the volatile part. November rainfall has ranged from 3 mm to 233 mm across the twenty years measured — a 230 mm spread around an average of 49 mm. The average is real but almost no individual November looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind sits around 19.7 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How November sits in the year

Temperatures hold steady either side: 28.1 °C in October, 25.6 here, 24.1 in December. Nothing about the timing within the month matters much. Rain has already shifted: 8 days fewer than October had.

Daylight in November

November sits at the dark end of Key West's year — 11 hours of daylight against 13.6 at midsummer, losing 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 27.2 °C in November — warm enough that the water offers no relief from the heat. The sea peaks at 29.9 °C in August and bottoms out at 24.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

November in Key West versus nearby

If Key West is one option among several, the nearby comparison is worth making. Miami is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Cape Coral is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: November is effectively as good as it gets here — 5 points behind January, which is inside the margin where the weather stops being the deciding factor and price starts being it.
