Weather in May
Temperature
May's onset is marked by a subtle temperature increase, moving from 74.3°F (23.5°C) in April to a still warm 82.6°F (28.1°C). In May, the temperature drops to an average of 62.6°F (17°C) at night.Heat index
For May, the heat index is calculated to be a hot 89.6°F (32°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
