Aruba weather by month
February and March are the clearest choices for Aruba if you want warm weather with relatively few rainy days; June is another good option. Daytime averages stay around 27-29°C, so choosing when to go is more about rain and sunshine than finding warmth. March averages just 5 rainy days. The catch comes later in the year, when rain becomes more frequent without bringing much relief from the heat, particularly overnight.

January to March: the strongest choice for sunshine
February and March offer a useful balance of sunshine, warmth and fewer rainy days. February averages 8 hours of sunshine and 6 rainy days, while March has 7 hours and 5 rainy days. January is just as warm, with daytime averages of 27°C, but its 11 rainy days make it a less clear choice if avoiding rain matters most. For travellers who prefer warmth without the higher daytime temperatures of later months, this is a sensible window. Pack light clothing and sun protection, but leave room for a light waterproof. Nights average 25°C throughout this period, so evenings stay warm rather than offering a cool break.
April to August: relatively little rain, but sunshine varies
April and May both average 5 rainy days, yet sunshine drops to 4 hours daily. That makes them reasonable choices for avoiding frequent rain, but not the strongest picks if sunshine is your main priority. June offers a useful compromise, with 5 hours of sun, 6 rainy days and daytime temperatures of 29°C. July brings slightly lower daytime temperatures and more sunshine, while August returns to 29°C with nights averaging 27°C. Keep outings flexible around the midday heat and choose loose, breathable clothes for evenings. Sea temperatures rise from 26°C in April to 28°C in August, making this period well suited to travellers who enjoy warm water.
September to December: warm seas with a greater rain risk
September remains hot, with daytime averages of 29°C, but rain becomes more frequent. The shift is clearer in October and November, which average 17 and 20 rainy days respectively. These months are harder to recommend for a trip built around spending every day outdoors, although sea temperatures remain warm at 28°C. December brings some improvement, with 15 rainy days and 6 hours of sunshine, but it is still a wetter choice than February or March. Choose this part of the year if warm air and water matter more than minimising rain. Keep plans adjustable and carry a light waterproof; evenings remain warm, so heavy layers are unnecessary for the outdoor temperatures.
