Daytime and night-time in July

The typical July day in Aruba peaks at 28.5°C, but that is an average: the warmest 10% of days reach 29.8°C or more. About 100% of days top 25°C and 1 in 11 pass 30°C. Nights average 26.3°C; one night in ten drops to 25.5°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest July day here reached 32.9°C (2020-07-31) and the coldest night 24.2°C (2008-07-15).

Rain in July

Sea temperature in July

Sunshine and daylight

Around 5.9 hours of sunshine a day (estimated from cloud cover), 12.7 hours of daylight: the sun rises about 06:22 and sets about 19:10 local time in mid-July. Average cloud cover is 53%.

Is July a good time to visit Aruba?

Hot days with little relief at night

The temperature is consistently high, but extreme daytime heat is not the main concern: only 9% of July days reach 30°C. Humidity of 81% is the bigger consideration for comfort, especially if you plan to spend much of the day walking outside. Keep the middle of the day flexible, with time for shade and breaks rather than a packed outdoor schedule. Pack loose, lightweight clothing and choose somewhere with air conditioning if warm nights affect your sleep. With average lows of 26.3°C, evenings are still warm, so do not count on a substantial cool-down once daylight fades.

Good swimming weather, with some rain to allow for

The sea is a strong reason to choose July: at 27.0°C on average, it suits travellers who dislike a chilly swim. Rain falls on about 7 days, so leave room to move outdoor plans around rather than assuming every day will stay dry. That does not mean those days are complete washouts, but the figures do not tell you when rain will arrive or how long it will last. Sunshine averages about 5.9 hours within 12.7 hours of daylight, leaving plenty of daylight without a promise of constant sun. July therefore suits a flexible swimming-and-relaxing holiday better than a trip that depends on clear skies throughout.
