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
Díli's coldest month, August, generally records average temperatures ranging from a high of 30.1°C (86.2°F) to a low of 20.1°C (68.2°F).
Heat index
The heat index for August is appraised at a very hot 35°C (95°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

UV index
January through
April, August through
December, with an average maximum UV index of 12, are months with the highest UV index. A UV Index reading of 11, and higher, represents an excessive health risk from unsafe exposure to UV radiation for the average person.
Note: In August, the maximum UV index of 12 transforms into these recommendations:
Implement all necessary safeguards, unprotected skin might suffer burns rapidly. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Enhance your sun protection with tightly woven, yet airy clothing. Directly after outdoor activities or swimming, a broad-spectrum sunscreen with SPF 30+ should be applied generously and reapplied frequently. Alert! The Sun's UV rays are heightened by the reflection of sand and water.
