Weather in May
Temperature
With the onset of May, Catherine observes a minor temperature ascent, with the average high-temperature adjusting from April's 78.6°F (25.9°C) to a still warm 84.9°F (29.4°C). Throughout May, Catherine records an average temperature of 66.6°F (19.2°C) at night.Heat index
For most parts of May, the heat index is evaluated at a very hot 95°F (35°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular significance for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
