Weather in May
Temperature
As Riverside transitions into May, the average high-temperature is observed to slightly rise from a moderately hot 78.4°F (25.8°C) in April to a tropical 86.2°F (30.1°C). Throughout the month of May, Riverside expects an average low of 65.3°F (18.5°C).Heat index
In May, the heat index is estimated at a fiery hot 98.6°F (37°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Sunshine

In May, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.Note: During May, 6 as the daily maximum UV index converts into the following advice:
Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Enhance your sun protection with tightly woven, yet airy clothing.
