Summer Weather in Key West

The summer months get hot in Key West, much like the rest of the sunshine state. You can expect an average high of 88 to 90 degrees and an average low of 80 degrees during June, July, and August. This is also the rainy season, so it’s a good idea to pack an umbrella.

Because of the hot temperatures and the high possibility of rain, the summer months present a great value when it comes to rental properties and other tourism rates.


Winter Weather in Key West

Winter weather in Key West is notably milder than in much of the rest of the southern states. This is because of the effects of the gulf stream in the Straits of Florida and the effects of the warm waters in the Gulf of Mexico. They keep the waters warm and the temperatures mild in this tropical destination.

Because of these factors, the temperature in Key West varies only about 15 degrees from summer to winter. You can expect a median temperature of around 75 degrees, and you will rarely see temperatures drop below 66 degrees.

Hurricane Season in Key West begins June 1 and ends on November 30th each year. However, the months of September and October are typically considered the off-season due to the higher possibility of hurricanes developing in those two months.

It is a hit or miss situation when it comes to trying to predict hurricanes in any part of the country. Key West is no different. A geographic area can go many years without seeing a strong storm of any kind. Or an area can be hit with multiple hurricane force storms in a season.

Thankfully, weather modeling is solid in today’s day and age, and storms are identified well in advance. If you are traveling to Key West during Hurricane season, it is important to remain flexible and keep an eye on storm forecasts.
