Weather in August
Temperature
The warmest period is August, when temperatures fluctuate between an average high of 28°C (82.4°F) and a low of 21°C (69.8°F).Heat index
The average heat index in August is evaluated at a tropical 32°C (89.6°F). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
