Weather in May
Temperature
The start of May brings a subtle shift in the average high-temperature, edging up from April's warm 76.8°F (24.9°C) to a still moderately hot 83.8°F (28.8°C). The average temperature during May nights is registered at an enjoyable 62.6°F (17°C).Heat index

Sustained activity might cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently underestimate the importance of resting and drinking fluids.
