Temperature

March's arrival registers an average high-temperature of a still hot 32.4°C (90.3°F), closely aligning with the temperature of the previous month. March nights present a stark temperature decrease to a refreshing 19.1°C (66.4°F).

Heat index

The heat index value for March is calculated to be a blistering 41°C (105.8°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

March and April, with an average relative humidity of 68%, are the least humid months.

Rainfall

March is the month with the least rainfall. Rain falls for 9.3 days and accumulates 18mm (0.71") of precipitation.

UV index

The months with the highest UV index are March through September, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for average individuals.
Note: In March, a regular UV index of 7 translates into these guidelines:
Deflect overexposure. Sun protection is a necessity. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
