Weather in May

May, the last month of the spring in Topsy, is another warm month, with an average temperature ranging between min 68.4°F (20.2°C) and max 84.7°F (29.3°C).

Temperature

In Topsy, the onset of May comes with a modest high-temperature shift, transitioning from April's 77.5°F (25.3°C) to a still warm 84.7°F (29.3°C). During the month of May, the nighttime temperature falls to an average of 68.4°F (20.2°C).

Heat index

May's mean heat index is evaluated at a hot 93.2°F (34°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
