Weather in May
Temperature
The shift into May brings a slight increase in the average high-temperature, moving from a warm 73.9°F (23.3°C) in April to a still moderately hot 81.9°F (27.7°C). An average nighttime temperature of 61.2°F (16.2°C) is recorded during May.Heat index
For May, the heat index is calculated to be a hot 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
