Aruba · 12.52°N 70.03°W · monthly climate normals, judged against the Tropical preset (mean 24–33 °C75–91 °F, anything but the monsoon)
Aruba fits the Tropical preset all year: mean temperatures run from 27 °C81 °F to 30 °C86 °F and rainfall runs 8–80 mm0.3–3.1 in a month.
Rain comes in the winter half of the year — November averages 80 mm3.1 in — while December to September is dry, with March down to 8 mm0.3 in. The mean temperature barely moves through the year, 27–30 °C81–86 °F, warmest in September.
Figures are 30-year monthly averages (WorldClim 2.1 monthly normals 1970–2000) for the 0.25° grid cell at 12.52, -70.03 — a climate guide, not a forecast.
Pick the weather you like and every month is judged against it — temperature above the month names, rain below.
Good time to go for a Tropical holiday: all year.

Reading the chart. Gold is good: the month fits what you picked. Any other colour names the reason it doesn't — the temperature bar can be too cold or too hot, the rain bar too dry, too rainy or monsoon. A faded gold bar is a half that fits while the other half fails; a gold month name means both fit.
What the verdicts mean. Temperature is the monthly mean, judged against the preset's band (mean 24–33 °C75–91 °F for Tropical). Rain is judged by each month's class within Aruba's own year rather than raw millimetres: dry under 60 mm2.4 in, showers 60–100 mm2.4–3.9 in, rainy from 100 mm3.9 in and 35 % of the wettest month. Too rainy is a rainy-season month the preset doesn't allow. Monsoon is the heaviest kind of rainy season — 180 mm7.1 in or more (120 mm4.7 in near the yearly peak) in a climate whose wettest month is at least three times its driest — so every monsoon month is rainy season too; the label says which kind.
