A minimal variation is noted in Iapu's average high-temperature at the onset of March, reaching a still warm 28.8°C (83.8°F) from February's 29.3°C (84.7°F). Iapu's temperature lowers to a mean of 19.1°C (66.4°F) during the nights in March.

Heat index

The average heat index in March is computed to be a sweltering 35°C (95°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
