Key Largo Weather

Key Largo, in the upper Florida Keys, is the largest island in the chain and the most northerly, and experiences a subtropical climate with wonderful warm weather. The island sits positioned between the Everglades to the north and the only living coral barrier reef in the USA to the east, and is known as one of the major dive capitals of the world. Winters in the Keys are typically 10C warmer than on the mainland, and the weather is generally drier.

 

Key Largo experiences two distinct seasons - the wet season, which runs from May to October, and the dry, running from November to April. Winters are the main tourist season, seeing pleasant warm days with little rainfall in Key Largo, and temperatures ranging from 27C in November to 24C in January. Humidity is low and comfortable at this time, with these months ideal for a beach holiday with plenty of water-based activities. There are between 7 - 9 hours of sunshine each day, night-time temperatures of 14C - 16C, and limited rainfall, with 30mm - 50mm falling each month during the winter.

 

The temperature heats up in April, and Key Largo sees the start of the wet season. By May the highs are around 30C, and the island sees 168mm of rain, increasing to 250mm by June. The humidity levels peak in July and conditions remain hot and sticky until September, although the ocean breezes do help to temper the high temperatures. There's rainfall each day until October, although the showers are short-lived and still accompanied by 9 - 10 hours of sunshine each day.
