Weather in May
Temperature
The arrival of May introduces a minor uplift in high-temperatures, adjusting from a warm 75.4°F (24.1°C) in April to a still moderately hot 81.5°F (27.5°C). Throughout May, Dennis records an average temperature of 63.5°F (17.5°C) at night.Heat index
During May, the heat index is calculated to be a hot 86°F (30°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
