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

June's presence marks an average high-temperature of a still tropical 33.6°C (92.5°F), subtly varied from May's 34.4°C (93.9°F). The average low-temperature of 26.1°C (79°F) is witnessed in Bangkok during June.

Heat index

The heat index value during June is calculated to be a burning hot 47°C (116.6°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
The metrics for the heat index are tailored for both shady environments and light winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
