, the first month of the autumn, in Pattaya
, is also a hot month, with temperature in the range of an average low of 25.2°C (77.4°F) and an average high of 31°C (87.8°F).
In Pattaya, the average high-temperature in September is relatively the same as in August
- a still tropical 31°C (87.8°F). In Pattaya, the average low-temperature is 25.2°C (77.4°F).
In September, the average heat index is appraised at a blistering 41.2°C (106.2°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'real feel', 'felt air temperature', 'apparent temperature', or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (pregnancy, differences in body mass, height, and shape, clothing). Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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 cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. 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. If the body can not disperse the excessive heat and body temperature reaches conditions of hyperthermia, above 37.5°C (99.5°F) to 38.3°C (100.9°F), thermal conditions are potentially life-threatening.
The average relative humidity in Pattaya is 81%.
In Pattaya, Thailand
, in September, during 17 rainfall days, 204.7mm (8.06") of precipitation is typically accumulated. In Pattaya, during the entire year, the rain falls for 106 days and collects up to 1110.7mm (43.73") of precipitation.
In Pattaya, the average water temperature is 29.1°C (84.4°F).Note
: For any water activity, surface water temperatures between 25°C (77°F) and 29°C (84.2°F) are considered as excellent and extremely pleasant for lengthened periods.
In Pattaya, the average length of the day is 12.2h.
through September, with an average of 5h of sunshine, are months with the least sunshine in Pattaya.
through September, with an average maximum UV index of 12, are months with the highest UV index in Pattaya. A UV Index of 11, and more, symbolizes an extreme threat to health from unprotected exposure to the Sun's UV rays for average individuals.Note
: The daily maximum UV index of 12 interpret into the following advice:
Practice all-important precautions. Light skin people may get burned in less than 5 minutes. 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. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes. 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.
