In Kanchanaburi, March's average high-temperature stands at a still very hot 37.3°C (99.1°F), closely related to the preceding month. A noticeable downturn in temperature characterizes the March nights, averaging at a warm 24.2°C (75.6°F).
Heat index
The average heat index in March is appraised at a burning hot 53°C (127.4°F).
Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
The heat index's values are generally associated with conditions in shade and light breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Remember, however, that not all shade structures offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Even on overcast days, a sunscreen with a sun protection factor of no less than 30 should be generously applied and reapplied, particularly after swimming or outdoor activities.
