Weather in May
Temperature
Observing a minor shift, the average high-temperature during May adjusts from April's warm 78.6°F (25.9°C) to a still moderately hot 85.5°F (29.7°C). Throughout the month of May, Riverview witnesses an average low-temperature of 65.5°F (18.6°C).Heat index
The heat index in May is appraised at a torrid 96.8°F (36°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Remember that heat index calculations are made for conditions in the shade with light wind. 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 a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
