Weather in Florida in July

How July compares

July is the 1st warmest month of the year in Florida. Within United States it is 3rd of 6 (United States in July). Against London's average high of 21.8°C in July, Florida is 9.0°C warmer by day and 11.4°C warmer at night.

Daytime and night-time in July

The typical July day in Florida peaks at 30.8°C, but that is an average: the warmest 10% of days reach 32.3°C or more. About 100% of days top 25°C and almost every pass 30°C. Nights average 24.9°C; one night in ten drops to 23.7°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest July day here reached 36.7°C (1998-07-03) and the coldest night 20.6°C (2010-07-08).

Rain in July

Wet (more than 8 rainy days): about 21 days with 1 mm or more, 138 mm in total. Year to year it varies a lot - the wettest July was 2018 with 327 mm, the driest 2015 with 41 mm. Humidity averages 80%, which makes the heat feel heavier than the thermometer suggests.

Sea temperature in July

The sea averages 29.5°C - warm enough to swim (22°c+). Depending on the year it ranges from 29.0°C to 30.0°C. For the warmest sea here, come in August (29.9°C).

Sunshine and daylight

Around 5.1 hours of sunshine a day (estimated from cloud cover), 13.6 hours of daylight: the sun rises about 06:38 and sets about 20:25 local time in mid-July. Average cloud cover is 62%.

Is July a good time to visit Florida?

It is a reasonable choice: hot days but expect showers. The best months for Florida on our scoring are March, April, November; months averaging 25°C or more: Apr, May, Jun, Jul, Aug, Sep, Oct, Nov.

Expect heat that lasts into the evening

July is Florida's warmest month, with average daytime temperatures 9°C above London's July level. Humidity of 80% makes that heat feel more wearing, especially when you are walking around rather than sitting by the water. Temperatures reach 30°C on 70% of days, so hot weather is something to plan around, not an occasional interruption. Choose loose, lightweight clothing and breathable footwear, and leave room for air-conditioned breaks around midday. Evenings are still warm enough for light clothes; they are not a reliable chance to cool down outdoors. This is a better fit for travellers comfortable with sustained heat than for anyone wanting long, active days outside.

Plan for rain, not uninterrupted sunshine

Rain is a regular part of July, so a rigid schedule of outdoor days is likely to be frustrating. About 21 days have measurable rain, although that does not mean each is a washout. There is around 5.1 hours of sunshine within 13.6 hours of daylight: plenty of time to arrange your day, but no promise of clear skies throughout it. Pack a lightweight waterproof and give yourself indoor alternatives rather than relying entirely on time outside. The combination of heat and wet weather is the compromise here. July can work well if you are relaxed about changing plans, but it is less suited to a holiday built around guaranteed sunshine.
