Escape the cold from December to February

While most of the northern hemisphere feels uninvitingly cold from December to February, Key West plays by its own rules. It’s not called endless summer for nothing.

A Key West day in the middle of winter typically sees daytime temperatures in the mid 70s (24°C). At night, temperatures on average don’t retreat below the mid 60s (18°C).

Even when you visit Key West between December and February, you need to take action to make sure that the sun doesn’t get the better of you. You might call it winter elsewhere, but in Key West — it’s still summer.

So tour Old Town of Key West, attend sunset celebration on Mallory Square and then head to Duval Street for dinner and world-class entertainment — all wearing your favorite summer outfit.

Enjoy the best weather from March to May

Do you want to visit Key West when the Florida island offers its most attractive weather? Then make your way to Key West in March, April or May.

At this time of the year, called spring elsewhere in America, days are clear and warm, but not yet outright sizzling. Expect average high temperatures hovering around the upper 70s and lower 80s (27°C).

How nice doesn’t that sound?

No matter if you target sightseeing or beachgoing, land based activities or water based pleasures, March through May is the perfect Key West period to visit Key West. Just make sure to pack your best sunglasses —  they will be needed.

Endure the dog days of summer between June and August

Testing the tolerance level of visitors, June to August is the most intense shade of Key West’s summer. During daytime the temperature frequently hits the 90s (32°C), and even at night it floats around 80°F (27°C).

You might think that sounds pretty bearable, but have Key West’s signature humidity of 70%+ in mind too. Because of the humidity, days feel significantly hotter than the number the thermometer shows.

This period of the year is called the dog days of summer for a reason. The combo of hot and humid can really make you feel uncomfortable.

It’s an unforgiving duo and one thing is certain: You’re going to sweat.

June, July and August is a time in Key West that you either love or hate. If you don’t mind boiling conditions, it’s a great time to visit Key West. But if you rather avoid those balmy day, this time of the year isn’t for you.

Score a good hotel deal from September to November

The Atlantic hurricane season officially begins in June and ends in November. Its most busy part is the time from mid-August to mid-October, with the very peak of action in September.

Will a hurricane hit Key West the next hurricane season or not? No one can know for sure, but chances are great that your Key West vacation won’t be interrupted by the weather gods.

In fact, September to November is a superb time to visit Key West on a budget. Because kids are back to school and the potential hurricane threat, you can often score sweet fall deals on Key West hotels.

November might be the overall best month of the year to visit Key West. Now the average daytime temperatures are back around the lower 80s (27°C), and it rains less than during the other fall and summer months.

Just know the risks and double check your travel insurance in case you plan a Key West visit between September and November. When it comes to travel plans and hurricanes, it’s definitely better to be safe than sorry.

Sweat with Hemingway in July

Discover the waters in August

The dog days of summer continue well into August. If you want to cool down a little bit, do as the locals do and go out on the surrounding waters. Those ocean breezes are certainly as appreciated as ever in August. For a complete salvation, try some Florida Keys snorkeling or diving.

Go big or go home in September

Do you feel lucky, or at least not unlucky? September can both be a beautiful and relatively cheap time to visit Key West. However, have in mind that September is the month when the Atlantic hurricane season is as most active.

Especially look out for the float carrying the year’s crowned Conch King and Queen.

Find a sweet spot in November

As October becomes November, the skies get clearer and, although the hurricane season officially lasts through November 30, the risk of an hurricane decreases day by day. Still it’s not yet high season in the Florida Keys, which means that Key West accommodations offer appealing rates. If you travel on a budget but want to avoid the peak of hurricane season, November is the best time to visit Key West.

With temperatures hovering around the mid 70s (24°C) in December, the appeal of spending the holidays in Key West is evident. Why shovel snow when you can shovel sunshine in Key West instead?
