Your June weather guide
HotWeather in Miami in June
June suits a Miami trip built around warm-water swimming and hot weather, but not one that depends on staying dry. Average daytime highs are around 29°C, nights remain near 25°C, and rain falls on about 20 days. For a UK traveller, the main adjustment is the combination of heat, humidity and little overnight cooling. Go if you can keep plans flexible; choose another month if dependable outdoor weather matters most.

How June compares
June is the 4th warmest month of the year in Miami and ranks 31st of 134 destinations we compare for June - see where else is hot in June. Within United States it is 4th of 6 (United States in June). Against London's average high of 19.6°C in June, Miami is 9.6°C warmer by day and 13.9°C warmer at night.
Daytime and night-time in June
The typical June day in Miami peaks at 29.2°C, but that is an average: the warmest 10% of days reach 31.0°C or more. About 100% of days top 25°C and 1 in 4 pass 30°C. Nights average 25.2°C; one night in ten drops to 23.8°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest June day here reached 33.9°C (2020-06-30) and the coldest night 21.7°C (2018-06-08).
Rain in June
Wet (more than 8 rainy days): about 20 days with 1 mm or more, 158 mm in total. Year to year it varies a lot - the wettest June was 1997 with 354 mm, the driest 1998 with 41 mm. Humidity averages 80%, which makes the heat feel heavier than the thermometer suggests.
Sea temperature in June
The sea averages 28.5°C - warm enough to swim (22°c+). Depending on the year it ranges from 28.0°C to 29.0°C. For the warmest sea here, come in August (29.9°C).
Sunshine and daylight
Around 4.8 hours of sunshine a day (estimated from cloud cover), 13.6 hours of daylight: the sun rises about 06:29 and sets about 20:13 local time in mid-June. Average cloud cover is 65%.
Is June a good time to visit Miami?
It is a reasonable choice: hot days but expect showers. The best months for Miami on our scoring are March, February, April; months averaging 25°C or more: Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov.
Hot days, warm nights and easy swimming
The heat is persistent rather than limited to occasional hot spells: days reach 25°C throughout June, while 28% reach 30°C. With humidity at 80%, lightweight, breathable clothing will be more useful than a suitcase full of layers. Keep strenuous outdoor plans away from midday and leave room for shaded or air-conditioned breaks. Evenings are warm too, so don't expect stepping outside after dark to provide much cooling. The sea is a clear reason to come, averaging 28.5°C: this is comfortable swimming weather without a chilly first dip. June therefore works well if you enjoy warmth on land and in the water, but less well if you need cool nights to feel comfortable.
Plan around rain, not uninterrupted sunshine
Rain is the main compromise. With about 20 rainy days, wet weather belongs in your plans rather than being treated as an unlikely interruption. Carry a compact umbrella or lightweight waterproof and keep indoor alternatives available instead of committing every day to outdoor time. There are about 4.8 hours of sunshine within 13.6 hours of daylight, so a long day does not mean continuous sun. That still leaves scope for swimming and time outside, but flexibility matters more than a tightly scheduled itinerary. If your holiday depends on dry conditions throughout, June is a weaker choice; if you can change plans without feeling the day is wasted, the warmth may justify the trade-off.
