June brings the hot summer to Aruba, with average temperatures in the range of 26.1°C (79°F) to 31.1°C (88°F). Temperatures in Santa Cruz rarely exceed 32.8°C (91°F) or fall below 25°C (77°F), and the average monthly humidity is constant at 77%. The northeast trade winds temper the heat to a certain degree. The brightest days see clear skies for 30% of the time, and the sunlight lasts for 9 hours. June 15 is the windiest day of the year, with an average daily wind speed of 34.6km/h (21.5mph). June 20 is the longest day in Oranjestad, with 12 hours and 52 minutes of daylight. A few showers wet the island occasionally, but June is mostly dry.
Expect the heat to rise with the progress of the summer. Keep an eye on the weather forecast for tropical storms before planning a trip. June sees a fair number of visitors in Aruba due to summer holidays but is uncomfortably hot for people from cold countries.
