The climate of Key West (Florida
- United States of America)
Key West is the most southerly located city on the mainland of
Florida. Because of its favorable climate it is very popular among sun
worshippers. The atmosphere and architecture are very different from
those in other cities in the United States. Relaxed, hippie-like and
full of atmosphere are the key words that describe this city best. Key
West has a subtropical climate. During the winter night time
temperatures hardly ever drop below 13-14 degrees Celsius (55-57
degrees Fahrenheit). Daytime temperatures during the winter are about
22-26 degrees Celsius (71-79 degrees Fahrenheit). During the winter
precipitation figures are low, only 6 days with precipitation can be
recorded per month. Key West also gets a lot of sunshine. From January
till April 40% of the time skies are clear blue, 40% of the time skies
are slightly clouded for a few hours per day and 20% of the time skies
are clouded. April is the sunniest month with sunshine for about 84%
of the time. October, November and December are the darkest months
with sunshine for ‘only’ 70% of the time.
Rain
Key West has a dry period from November till the second part of May.
During this period about 50 millimeters of precipitation falls which
is about 35% of the national average of 75 millimeters per month. From
the second part of May chances of precipitation rapidly increase as
well as the amount of precipitation that may fall within a short
period of time. The wettest period is from the second part of August
till the end of September with 150-180 millimeters of precipitation
per month.
Wind
Average wind speeds are highest during the dry period from November
till April. On average the wind blows with a speed of 18-20 kilometers
per hour during this period. From May till October wind speeds are
slightly lower, about 14-18 kilometers per hour. This is rather
surprising since hurricane season is from June till November. During
this period tropical depressions pass over the Caribbean increasing
the risk of tropical storms and hurricanes. The risk of Key West
getting hit by a hurricane is not that high. However, the weather is
influenced a few times per year by storm activity in the vicinity.
Humidity figures
Average humidity figures are about 75% all year round. During the
morning humidity figures may be slightly higher, during the afternoon
slightly lower. Especially during the afternoon humidity figures here
are higher than the national average. This in combination with high
temperatures may cause things to feel muggy.

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
