Weather in May
Temperature
As May begins, there's a slight increase in the average high-temperature, moving from 74.1°F (23.4°C) in April to a still warm 81.5°F (27.5°C). The low-temperature averages to a comfortable 61.2°F (16.2°C) during the nights of May.Heat index
May's average heat index is appraised at a hot 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
