Best Time To Visit Key West
General
Located in the southernmost point of the United States, Key West gives us shorts-and-flip-flops weather year-round. Ahhhhh. Key West weather is influenced by our proximity to the Gulf of Mexico and the Caribbean Sea, resulting in relatively consistent temperatures but with distinct wet and dry seasons. So, when is the best time to visit Key West? If one is better than any other, what is the best month to go to Key West?? Can you swim in Key West all year??? These are all good questions that we hear often. Here are the facts, straight from a Conch’s mouth (i.e. a local):
In terms of weather, the best time to visit Key West is March through May, and in November and December. And yes, you can swim year-round in Key West!
In this article, we’ll break down Key West weather, including an overview of our weather patterns and a monthly breakdown of what you can expect, share some travel tips, and provide you with a guide to what’s going on in the Keys during the best weather months. It’s your Key West travel guide: weather edition. Let’s get into it!
Overview of Key West Weather Patterns
As we mentioned, there is a wet and dry season in Key West. The bulk of the year is marked by the wet season, i.e. April through November. The dry season tends to settle in in November and lasts through March.
You could say that the wet season is in two parts, too. From April through about August, “wet” generally means daily rain and, in the summer months, an afternoon thunderstorm. But neither usually lasts long; they blow over pretty fast. In September and October, though, we keep our eyes on the Gulf and the Atlantic for tropical storms and hurricanes.
OK, now let’s look at what you can expect during the “best time” windows we’ve identified, starting with some monthly weather averages.
Weather Breakdown: March – May
This first best weather period has one foot in the dry season and the other in the wet season. That means in March, as temperatures and humidity start to increase, we start to see more frequent rain showers. Afternoon thunderstorms are to be expected once we’re in April and are pretty much a guarantee come May.
March
Average high temperature: 78°F; average low: 68°F
Average water temperature: 75°F
Average sunset time: 6:38 PM
April
Average high temperature: 81°F; average low: 71°F
Average water temperature: 78°F
Average sunset time: 7:00 PM
May
Average high temperature: 84°F; average low: 75°F
Average water temperature: 81°F
Average sunset time: 7:27 PM
Now, keep in mind that June through October is usually lovely in Key West too – it’s just hot and humid, with minimal variation between day and night. This time of the year is considered the Key West off-season. In fact, the months of September and October are generally the cheapest months to visit Key West. Although these are the best months for Key West travel deals on accommodations, activities, and dining, they are not necessarily the least crowded. We see a dip in tourism during these months compared to peak season, but Key West attracts visitors throughout the year.
Weather Breakdown: November – December
When most of the US is preparing for winter, we’re gearing up for the most wonderful time of the year (for totally different reasons) down here in Key West! Dry season kicks in and the water temperature is still chef’s kiss perfect.
November
Average high temperature: 81°F; average low: 71°F
Average water temperature: 79°F
Average sunset time: 5:37 PM
December
Average high temperature: 77°F; average low: 66°F
Average water temperature: 75°F
Average sunset time: 5:33 PM
Again, January and February are also picturesque in the Keys. The water dips to an average of 65°F, making it a little too chilly for some folks – and also, still plenty warm for others.
Best Times To Visit Key West For Various Activities
From an activity point of view, plenty is going on in the Keys during these “best” months. With the sun setting later and later March through May, you have an enormous window for beach time, water sports, and incredible sunset experiences – including the daily Sunset Celebration at Mallory Square. Of course, the water is always crystal clear down here, so you have access to all things Key West in November and December too.
