Weather in August
Temperature
The start of August sees the average high-temperature at a still warm 83.5°F (28.6°C), showing little difference from July's 85.3°F (29.6°C). Throughout August, a steady low-temperature average of 67.8°F (19.9°C) is noted.Heat index
The heat index for August is calculated to be a tropical 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Boost your sun resistance with garments that are densely woven yet spacious. Stay aware! UV radiation is magnified when reflecting off sand and water.
