Weather in May
Temperature
With the onset of May, O'Donnell observes a minor temperature ascent, with the average high-temperature adjusting from April's 77°F (25°C) to a still moderately hot 84.2°F (29°C). Nighttime in May brings a stark departure from the daily high, resting at an average low-temperature of 61.9°F (16.6°C).Heat index
May's average heat index is estimated at 84.2°F (29°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.In the scope of the heat index, its values resonate with shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

Deflect overexposure. Sun protection is a necessity. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
