Temperature

In Phuket, March is identified by the highest average temperatures, reaching a peak of 34°C (93.2°F) and a low of 25.4°C (77.7°F).

Heat index

March's average heat index is estimated at a blazing hot 47°C (116.6°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
Given the heat index, its values are aligned with shaded sites and gentle winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
