Weather in August
Temperature
The warmest period tends to be August, when average temperatures fluctuate between a high of 29.2°C (84.6°F) and a low of 14.4°C (57.9°F).Heat index
August's average heat index is estimated at a hot 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
