Weather in May
Temperature
May's onset is marked by a subtle temperature increase, moving from a warm 75.7°F (24.3°C) in April to a still moderately hot 82.4°F (28°C). Cool records an average nighttime low-temperature of 63.3°F (17.4°C) throughout May.Heat index
The heat index value during May is appraised at a tropical 87.8°F (31°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 remain especially vital for babies and toddlers. 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.

Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
