June in
Yangon marks the continuation of the monsoon season, dominated by wet, cloudy, and humid conditions. The rain showers are constant, resulting in a verdant and fresh ambience across the city. A gradual decrease in temperature forms the backdrop for the heightened rainfall this month. Though the sun often hides behind the monsoon clouds, the daylight durations are relatively longer, offering ample daylight. Safety precautions against monsoon-related illnesses become crucial during this month due to the high humidity and persistent rains.
Temperature
June brings a minor shift in the average high-temperature in Yangon, adjusting from a tropical 33.4°C (92.1°F) in
May to a still hot 30.2°C (86.4°F). Yangon's nights in June experience an average temperature drop to a warm 24.5°C (76.1°F).
Heat index
June's heat index is estimated at a blistering 40°C (104°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Ensure all key precautions. Defense against sun exposure is critical. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. A sunscreen with at least SPF 30 should be used liberally and reapplied frequently on cloudy days, especially after swimming or an outdoor workout.
