The last month of the summer, August
, is another warm month in Yangon
, with an average temperature varying between 24.1°C (75.4°F) and 29.6°C (85.3°F).
The coldest month is August, with an average high-temperature of 29.6°C (85.3°F) and an average low-temperature of 24.1°C (75.4°F).
The average heat index in August is computed to be a very hot 38°C (100.4°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'felt air temperature', 'real feel', 'feels like', or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Additional factors like wind, differences in body mass, height, and shape, pregnancy, and activity influence one's weather impression. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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 is vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.
The most humid month in Yangon is August, with an average relative humidity of 87%.

On the first day of August in Yangon, Myanmar, sunrise is at 05:45 and sunset at 18:37. On the last day of the month, sunrise is at 05:51 and sunset at 18:19 +0630.
In August, the average sunshine is 3h.
, with an average maximum UV index of 12, are months with the highest UV index in Yangon. A UV Index estimate of 11, and higher, represents an extreme health hazard from exposure to the Sun's UV radiation for the average person.Note
: The daily maximum UV index of 12 in August interpret into the following advice:
Practice all-important precautions. Light skin people may get burned in less than 5 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise.
