Weather in May
Temperature
May introduces a minor temperature shift, with average high-temperatures adjusting from April's 74.8°F (23.8°C) to a still warm 81.3°F (27.4°C). San Leon's average temperature during the nights of May is recorded at an agreeable 72.5°F (22.5°C).Heat index
The heat index value during May is estimated at a tropical 86°F (30°C). One might feel worn out with persistent exposure and activity, resulting in heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
