June invites a drier season in
Díli compared to the previous months. Setting itself apart from the upcoming wetter
July, June records a rainfall amount of only 58mm (2.28"). Despite diminished frequency of rain, the city maintains its tropical warmth, without any significant drop in temperature. As a result, the month offers consistent daylight hours and a considerable amount of sunshine time, ideal for sightseeing and exploring the city. Moreover, the reduced humidity levels during June make the weather even more enjoyable.
Temperature
Díli records an average high-temperature of a still tropical 30.7°C (87.3°F) as June arrives, nearly mirroring the previous month's climate. The nights of June anticipate an average low-temperature of 21.9°C (71.4°F).
Heat index
The heat index value during June is calculated to be a fiery hot 37°C (98.6°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

UV index
June and July, with an average maximum UV index of 10, are months with the lowest UV index. A UV Index estimate of 8 to 10 represents a very high threat to health from unprotected exposure to Sun's UV rays for average individuals.
Note: The daily high UV index of 10 during June translates into the following recommendations:
Take special precautions, as unprotected eyes and skin can be burned and damaged quickly. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Following every swim or outdoor workout, a sunscreen with an SPF of not less than 30 should be liberally applied and re-applied frequently, even on overcast days. Be cautious! Sand and water surfaces make the Sun's UV rays more potent.
