Weather in May
Temperature
As May arrives, Donegal's weather shows a minor increase in high-temperatures, edging from April's moderately hot 75°F (23.9°C) to a still warm 82°F (27.8°C). Donegal encounters a steady low-temperature average of 64.4°F (18°C) throughout the month of May.Heat index
During May, the heat index is computed to be a hot 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
