Heat index

March's mean heat index is computed to be 29°C (84.2°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.

Humidity

March and April, with an average relative humidity of 60%, are the least humid months.

Note: In March, the maximum UV index of 6 suggests this advice:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
