Weather in May
Temperature
The advent of May reveals an average high-temperature of a tropical 86°F (30°C), showing minimal difference from the prior month. Throughout May, Norman experiences a low-temperature average of 68.2°F (20.1°C).Heat index
In May, the heat index is computed to be a very hot 96.8°F (36°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
