October weather forecast
Bangkok, Thailand

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

The start of October sees the average high-temperature at a still hot 32.6°C (90.7°F), showing little difference from September's 32.8°C (91°F). During October, the average low-temperature is a warm 24.8°C (76.6°F).

Heat index

October's average heat index is appraised at a life-threatening hot 46°C (114.8°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
The heat index's values are generally associated with conditions in shade and light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. 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 are highly critical to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. 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 and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Employ every crucial safety step. Those with fair skin could experience burns in a matter of minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Watch out! Reflections from sand and water can surge UV radiation exposure.
