Weather in August
Temperature
Terre-Neuve starts August with an average high-temperature of a still hot 30.4°C (86.7°F), a minor shift from July's 30.7°C (87.3°F). Nighttime temperature dips to a mean of 23.3°C (73.9°F) during August.Heat index
The heat index for August is calculated to be a torrid 38°C (100.4°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

A UV Index value of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: A daily maximum UV index of 7 in August translates into the following instructions:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
