June weather forecast
Bangkok, Thailand

With the arrival of June, Bangkok experiences a continuation of the monsoon season. Pleasingly, the heat starts to retreat, facilitating more comfortable weather conditions for residents and visitors alike. The heightened levels of precipitation continue to be the climate's highlight, keeping the city's plush greenery refreshed. Furthermore, receding temperatures and moisture-packed winds from nearby storms help to alleviate the city's normally high heat levels. The end of the month sees a slight decrease in rainfall, gearing up for July's comparable weather.

Temperature

Bangkok records an average high-temperature of a still hot 33.6°C (92.5°F) as June arrives, nearly mirroring the previous month's climate. In June, Bangkok experiences an average nighttime temperature of 26.1°C (79°F).

Heat index

In June, the average heat index is estimated at a life-threatening hot 47°C (116.6°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

In Bangkok, the average relative humidity in June is 74%.

UV index

The months with the highest UV index are February through September, with an average maximum UV index of 12. A UV Index reading of 11, and higher, represents an ultimate health vulnerability from unsafe exposure to UV radiation for average individuals.
Note: The UV index of 12 during June leads to these advisories:
Take all required precautions, as unprotected skin and eyes can burn in minutes. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Apply and frequently reapply a broad-spectrum SPF 30+ sunscreen after every two hours, or immediately after a swim or outdoor exercise. Attention! The reflection of both water and sand can increase the intensity of UV rays.
