Weather in May

May, the last month of the spring in San Augustine, is another warm month, with an average temperature ranging between max 84.9°F (29.4°C) and min 64.2°F (17.9°C).

Temperature

The start of May brings a subtle shift in the average high-temperature, edging up from April's moderately hot 77.2°F (25.1°C) to a still warm 84.9°F (29.4°C). The temperature lowers to an average of 64.2°F (17.9°C) during May nights.

Heat index

During May, the heat index is estimated at a very hot 95°F (35°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
