May weather forecast
Arapoema, Brazil

The last month of the autumn, May, is another tropical month in Arapoema, Brazil, with an average temperature ranging between min 21.8°C (71.2°F) and max 31.3°C (88.3°F).

Temperature

The arrival of May marks a slight shift to an average high-temperature of a still hot 31.3°C (88.3°F) from April's 30.9°C (87.6°F). The temperature dips to an average of 21.8°C (71.2°F) during May nights.

Heat index

May's mean heat index is estimated at a scorching 41°C (105.8°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. 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. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
