Weather in March
Temperature
With the onset of March, the average high-temperature stands at a hot 30.1°C (86.2°F), closely aligned with February's 29.3°C (84.7°F). Nighttime temperatures hover around an average low of 21°C (69.8°F) in March.Heat index
The heat index value for March is calculated to be an extremely hot 40°C (104°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
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. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
