September weather forecast
Yangon, Myanmar

September carries the tail end of the monsoon in Yangon. After peaking in August, the amount of rainfall starts to decline, and a slight increase in temperature is noticeable. Despite the continuance of the rainy conditions, a fading monsoon breathes fresh life into the city’s vibrant landscapes. Evenings in September turn pleasant with the cessation of showers and temperatures dropping at night. With a reduction in cloud cover, there is a marginal increase in sunshine hours, slightly brightening the days.

Temperature

Yangon's average high-temperature marks a hot 30.4°C (86.7°F) with the advent of September, closely mirroring that of the preceding month. September's nights in Yangon observe an average temperature of 24.2°C (75.6°F).

Heat index

Throughout September, the heat index is estimated at a scorching 41°C (105.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

In Yangon, the average relative humidity in September is 85%.

UV index

The months with the highest UV index are March through September, with an average maximum UV index of 12. A UV Index reading of 11, and higher, represents an ultimate health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: The average daily UV index of 12 in September transforms into the following instructions:
Undertake all critical precautions. Protection from sun harm is vital. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious. 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.
