Temperature

Iona's warmest month, August, registers temperatures that range from a high of 88.9°F (31.6°C) to a low of 79.7°F (26.5°C).

Heat index

Throughout August, the heat index is estimated at a blistering 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Humidity

The average relative humidity in August is 74%.

Rainfall

The month with the most rainfall in Iona is August, when the rain falls for 24 days and typically aggregates up to 3.94" (100mm) of precipitation.

UV index

The months with the highest UV index in Iona are May through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: A maximum high UV index of 7 in August translates into the following recommendations:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Heads up! UV intensity is amplified by reflections from water and sand.
