March weather forecast
Nuku'alofa, Tonga

March weather appears to retain the general climate of February, without any drastic weather transformations. Notable is the scarce reduction of monthly average temperature with a peak of 29.6°C (85.3°F) from the preceding peak of 29.9°C (85.8°F) in February. The diminishing rainfall and slightly shorter daylight token the inception of the transition towards the less humid months. Sea temperatures remain more or less constant. The UV index stays at its peak, necessitating continued use of sun protection.

Heat index

The heat index in March is calculated to be a torrid 36°C (96.8°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Enforce every vital precaution. Those with light skin could endure burns in a matter of minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Enhance your sun protection with tightly woven, yet airy clothing. Even on overcast days, ensure the application and frequent reapplication of sunscreen with at least an SPF 30, especially post swim or outdoor exercise. Heads up! UV intensity is amplified by reflections from water and sand.
