Weather in May
Temperature
As Hollis transitions into May, the average high-temperature is observed to slightly rise from a warm 75.2°F (24°C) in April to a still moderately hot 83.1°F (28.4°C). A striking departure from daytime highs to an average low-temperature of 61.3°F (16.3°C) is witnessed during May.Heat index
The heat index for May is estimated at 84.2°F (29°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Heat index determinations are made taking into account the shade and light air movements. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', offers an insight into how hot it feels when we factor in moisture content. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
