May's arrival coincides with a marginal rise in the average high-temperature, moving from April's moderately hot 75.7°F (24.3°C) to a still warm 82.2°F (27.9°C). An average low-temperature of 66.2°F (19°C) is noted during the month of May.Heat index
The heat index for May is computed to be a hot 87.8°F (31°C). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children.

Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
