October in
Bangkok witnesses a culmination of the monsoon season and the inception of the city's much-awaited dry season. The city's weather map exhibits declining trends in rainfall and humidity levels, making the outdoor environment more pleasing. A decrease in cloud coverage makes for extended periods of sunshine, much to the delight of the residents. Despite the receding moisture levels, wave activities remain high due to the relatively high sea temperature. The decreasing rainfall paves the way for lower temperatures in
November, promising a dry and comfortable climate.
Temperature
Bangkok's shift into October is marked by a subtle change to a still tropical 32.6°C (90.7°F) from
September's 32.8°C (91°F) in temperature. Bangkok, in October, observes a steady average low-temperature of 24.8°C (76.6°F).
Heat index
The heat index for October is estimated at a burning hot 46°C (114.8°F).
Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Heat index evaluations are typically in the context of light winds and shaded environments. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
Humidity
The average relative humidity in October in Bangkok is 78%.

Carry out all important precautions, unprotected skin could get burns in no time. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Always opt for UVA and UVB-resistant sunglasses on radiant days. Apply and frequently reapply a broad-spectrum SPF 30+ sunscreen after every two hours, or immediately after a swim or outdoor exercise. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
