Weather in July
Temperature
July stands out as Donegal's warmest month, with temperatures ranging between an average high of 81.1°F (27.3°C) and a low of 60.1°F (15.6°C).Heat index
July's average heat index is computed to be a hot 86°F (30°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. 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 primarily vital for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
