Temperature

The arrival of March brings an average high-temperature of a still tropical 33.8°C (92.8°F), nearly identical to February's 31.3°C (88.3°F). In March, Chiang Rai endures a notable temperature shift from day to night, with lows averaging at a comfortable 16.9°C (62.4°F).

Heat index

March's heat index is appraised at a blistering 42°C (107.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Take all critical precautions, unprotected skin might burn swiftly. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Sunscreen of at least SPF 30 should be applied generously and reapplied often on overcast days, especially post swim or outdoor exercise.
