Weather in May
Temperature
A minimal variation is noted in Iona's average high-temperature at the onset of May, reaching a still moderately hot 84.7°F (29.3°C) from April's 81.1°F (27.3°C). In the month of May, Iona experiences an average low-temperature of 73°F (22.8°C).Heat index
For most parts of May, the heat index is evaluated at a hot 93.2°F (34°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for the average person.Note: The daily high UV index of 7 during May translates into the following recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days. Attention! UV strength is notably upped by the reflection of sand and water.
