Weather in August
Temperature
August brings an average high-temperature of a still moderately hot 83.8°F (28.8°C), nearly identical to the preceding month. Jay Em, in August, experiences an average temperature of 62.8°F (17.1°C) at night.Heat index
The average heat index in August is computed to be 84.2°F (29°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
