Weather in May
Temperature
May marks a minor ascent in the average high-temperature, adjusting from April's agreeable 72.9°F (22.7°C) to a warm 81°F (27.2°C). In May, Erin encounters an average low-temperature of 59.7°F (15.4°C) during the night.Heat index
During May, the heat index is appraised at a tropical 86°F (30°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
