Heat index
The heat index value during July is calculated to be a tropical 30°C (86°F). Fatigue might occur with continuous exposure and activity, potentially causing heat cramps.
In reference to the heat index, it's for places in shade and with a slight wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for 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.

With the absence of protection, damage to skin and eyes can occur instantly. Ensure precautions are taken. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. For optimal sun protection, use sunscreen of no less than 30 SPF. This not only prevents sunburn but also reduces radiation damage.
