Weather in May
Temperature
In May, the average high-temperature marginally rises from 77.9°F (25.5°C) in April to a still moderately hot 83.8°F (28.8°C). The temperature dips to an average of 68°F (20°C) during May nights.Heat index
For most parts of May, the heat index is calculated to be a hot 93.2°F (34°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
