August ushers in subtly increasing humidity which is typical for this period in
Díli. Following the trend of
July, the city has a monthly rainfall record of merely 12mm (0.47"). Despite this minimal increase, August's weather continues to be significantly drier than adjacent months. The arrival of
September will introduce higher rainfall levels, making August the last dry month of the year. The weather remains warm but not overly hot, and the city basks in an abundance of sunshine throughout the month.
Temperature
With average temperatures fluctuating between a high of 30.1°C (86.2°F) and a low of 20.1°C (68.2°F), August stands out as the coldest month.
Heat index
The heat index in August is computed to be a torrid 35°C (95°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
Humidity
August is the least humid month, with an average relative humidity of 70%.

UV index
The months with the highest UV index in Díli are
January through
April, August through
December, with an average maximum UV index of 12. A UV Index value of 11, and more, symbolizes an extreme threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: The daily maximum UV index of 12 in August interprets into the following advice:
Undertake all critical precautions. Protection from sun harm is vital. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Prompt application of a broad-spectrum sunscreen, SPF 30+, is necessary after a swim or an outdoor workout and it should be re-applied every two hours. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
