Weather in August
The ideal sea water temperature of 25°C (77°F) and only 0.4 rainfall days makes August the best time for swimming and other water activities.
Temperature
Istro's warmest weather arrives in August, when temperatures average a high of 28.1°C (82.6°F) and a low of 23.7°C (74.7°F).Heat index
For most parts of August, the heat index is evaluated at a hot 30°C (86°F). Persistent activity under exposure might lead to a feeling of weariness, with subsequent heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection.
