June weather forecast
Pattaya, Thailand

June, the first month of the summer in Pattaya, is also a hot month, with an average temperature fluctuating between 31.7°C (89.1°F) and 26.3°C (79.3°F).

Temperature

In June, the average high-temperature is relatively the same as in May - a still hot 31.7°C (89.1°F). In Pattaya, the average low-temperature is 26.3°C (79.3°F).

Heat index

In June, the average heat index is computed to be a blistering 42.1°C (107.8°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature', 'real feel', 'apparent temperature', or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional factors like pregnancy, wind, metabolic differences, 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 particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

The average relative humidity in June in Pattaya is 77%.

UV index

February through September, with an average maximum UV index of 12, are months with the highest UV index. A UV Index reading of 11, and higher, represents an excessive health risk from exposure to the Sun's UV rays for the average person.
Note: The average daily UV index of 12 in June transform into the following instructions:
Practice all essential precautions. Protection against sun damage is crucial. 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. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects. A broad-spectrum sunscreen of SPF 30+ should be liberally applied and re-applied every two hours, and immediately after an outdoor workout or a swim. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
