March indicates an arrival of more prominent tropical weather characteristics. Heat levels rise moderately from
February, while rainfall escalates considerably, signifying a transition towards
Ko Lanta’s rainy season. Darker cloud cover becomes prevalent, the number of rainfall days increases to a monthly total of 3 days, and the downpours become more sustained. Despite the changes, the daylight hours continue to grow longer, lending more time for sightseeing and outdoor enjoyment. As the month transitions to
April, expect an even greater surge in rainfall and an increase in humidity.
Temperature
March, marked by an average high-temperature of 34.1°C (93.4°F) and a low-temperature of 24.6°C (76.3°F), is the warmest month.
Heat index
The heat index for March is computed to be a blazing hot 50°C (122°F).
Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
