Weather in May

May, the last month of the spring in Rio Grande, is another hot month, with an average temperature ranging between min 23.8°C (74.8°F) and max 30.9°C (87.6°F).

Temperature

The average high-temperature in May, at a still tropical 30.9°C (87.6°F), reveals a modest deviation from April's 32.3°C (90.1°F). In the month of May, the temperature generally rests at an average low of 23.8°C (74.8°F).

Heat index

The average heat index in May is computed to be an extremely hot 41°C (105.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
