Temperature

Entering March, the average high-temperature is recorded at a still tropical 32.4°C (90.3°F), exhibiting a minimal shift from February's 31.2°C (88.2°F). A considerable shift from the daytime highs is observed during March nights, with an average low of 17.8°C (64°F).

Heat index

The heat index value during March is appraised at a fiery hot 39°C (102.2°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

With an average relative humidity of 63%, March is the least humid month.

Rainfall

In March, the rain falls for 6.7 days. Throughout March, 9mm (0.35") of precipitation is accumulated. Throughout the year, there are 181.4 rainfall days, and 1055mm (41.54") of precipitation is accumulated.

UV index

The months with the highest UV index are January through August, October through December, with an average maximum UV index of 6. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.
Note: The maximum UV index, 6 during March, leads to the following recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
