Weather in August
Temperature
August is the month when Islitas experiences its warmest temperatures, averaging a high of 100°F (37.8°C) and a low of 79.9°F (26.6°C).Heat index
During August, the heat index is appraised at a blazing hot 116.6°F (47°C). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

It is essential to prioritize protection. Unprotected skin and eyes can suffer rapid harm. 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. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
