Weather in August
Temperature
During July and August, Valparaiso experiences its peak temperatures, averaging a high-temperature of 88.3°F (31.3°C).Heat index
August's mean heat index is appraised at a fiery hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for average individuals.Note: During August, 7 as the daily maximum UV index converts into the following advice:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Warning! Sand and water reflections boost the intensity of UV exposure.
