March sees a continuation of warm weather in
Bangkok,
Thailand with a noticeable ascent in mercury levels. This month reaches a yearly high temperature of 34.3°C (93.7°F), starting an intensely warm period in the city. However, residents and visitors relish the extended daylight duration of 12.1 hours, allowing ample time for outdoor adventures. Despite the heat, the rain showers increase marginally signaling the onset of the wet season. As the city gears up for the impending monsoon season, the escalating sea temperatures keep beach-goers satisfied.
Temperature
Bangkok greets March with an average high-temperature of a still tropical 34.3°C (93.7°F), marking a slight deviation from the preceding month. During the nights in March, an average low-temperature of 25.9°C (78.6°F) is observed.
Heat index
In March, the average heat index is estimated at a blazing hot 49°C (120.2°F).
Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Remember that heat index calculations are made for conditions in the shade with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. 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 remain especially vital for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
Humidity
The average relative humidity in March is 72%.
Rainfall
In Bangkok, in March, during 3 rainfall days, 42mm (1.65") of precipitation is typically accumulated. In Bangkok, during the entire year, the rain falls for 128 days and collects up to 1648mm (64.88") of precipitation.
Sea temperature
In Bangkok, in March, the average water temperature is 28.3°C (82.9°F).
Note: In water activities such as swimming and diving, temperatures from 25°C (77°F) to 29°C (84.2°F) are deemed highly pleasurable for extended periods without any unease.
Daylight
In Bangkok, the average length of the day in March is 12h and 4min.
On the first day of the month, sunrise is at 06:34 and sunset at 18:26. On the last day of March, sunrise is at 06:14 and sunset at 18:29 +07.

UV index
The months with the highest UV index are
February through
September, with an average maximum UV index of 12. A UV Index of 11, and more, symbolizes an ultimate health vulnerability from exposure to the Sun's UV rays for ordinary individuals.
Note: In March, the maximum UV index of 12 suggests this advice:
Ensure every key safety measure. People with light skin might sustain burns in fewer than 5 minutes. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Despite the cloudy weather, sunscreen with a sun protection factor of at least 30 should be liberally applied and reapplied, including after a swim or outdoor activity. Attention! The reflection of both water and sand can increase the intensity of UV rays.
