Weather in May
Temperature
The arrival of May signals a slight increase in the average high-temperature, moving from 74.8°F (23.8°C) in April to a still warm 82.8°F (28.2°C). An average low-temperature of 62.2°F (16.8°C) is noted during the nights in May.Heat index
For May, the heat index is appraised at a hot 86°F (30°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Be advised, the heat index considers values for conditions in shade and with a light breeze. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.

Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection.
