What to Pack: Since nighttime lows only dip down to 69 degrees Fahrenheit 20 degrees Celsius at their lowest, you might not need to worry about bringing a sweater anymore, but you might still consider a long-sleeved shirt for evenings. On average, it rains or snows a smalll amount: consistently 3 times per month. Temperature and Dew Point There is only a single weather station, , in our network suitable to be used as a proxy for the historical temperature and dew point records of Key West. Daylight saving time is observed in Key West during 2019, but it neither starts nor ends during April, so the entire month is in daylight saving time. The windiest month is March, followed by April and November.
We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. The month of May in Key West experiences very rapidly increasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy increasing from 35% to 57%. If you are , it is important to note that Key West will require a mandatory evacuation if a storm is headed toward the city. Down in they were very scattered and when out on the boats we actually sailed around them one evening. Weather data is prone to errors, outages, and other defects.
With good weather conditions, this month is a good time to go in that area. Estimated Tourism by Month Overall Key West Travel Experience byÂ Season Spring March throughÂ May Humidity and temperatures combine to make this season feel warm. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night. The lowest chance of rain or snow occurs around early to mid May. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.
The temperature rises to 31°C. Prices for hotels and flights will be most expensive during these months, though you can save if you purchase well in advance. The average daily incident shortwave solar energy in Key West is decreasing during May, falling by 1. On the flip side this corresponds to an average of 11. The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed both rain and snow fell in the same day. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. The chance that a given day will be muggy in Key West is rapidly increasing during April, rising from 61% to 74% over the course of the month.

For reference, on June 20, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 70%, while on March 6, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 73%.
While having the tremendous advantages of temporal and spatial completeness, these reconstructions: 1 are based on computer models that may have model-based errors, 2 are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and 3 have particular difficulty with the weather in some coastal areas, especially small islands. Â Low Â°C Jan 24. A wet day is one with at least 0. For reference, on November 7, the windiest day of the year, the daily average wind speed is 14. While May is a little warmer than I like, it is also the month when most places have finally switched their room rates to their lower shoulder rates, so that's why I go then and not in April! For reference, the year's highest daily chance of a wet day is 59% on September 16, and its lowest chance is 12% on March 20.

For reference, on July 3, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 29, the least muggy day of the year, there are muggy conditions 42% of the time. This section reports on the wide-area average surface temperature of that water. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. When is the best time to go to Key West? The area within 2 miles of Key West is covered by water 59% and artificial surfaces 37% , within 10 miles by water 95% , and within 50 miles by water 99%.
Lower dew points feel drier and higher dew points feel more humid. Â June — August is the slowest season for tourism inÂ Key West, so lodging and other accommodations may cost less than usual. The average surface water temperature in Key West is gradually increasing during May, rising by 3°F, from 79°F to 82°F, over the course of the month. Over the course of April in Key West, the length of the day is increasing. In this report, we use a base of 50°F and a cap of 86°F. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.
