Temperature

March's advent in Hua Hin denotes a minor fluctuation in the average high-temperature to a still hot 32.4°C (90.3°F) from February's 31.3°C (88.3°F). Hua Hin observes an average low-temperature of 24.6°C (76.3°F) during March.

Heat index

March's average heat index is computed to be a blisteringly hot 43°C (109.4°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. 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 and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
