Weather in August
Temperature
With the advent of August, Halley experiences an average high-temperature of a still tropical 92.3°F (33.5°C), mirroring a close resemblance to the previous month. In August, Halley experiences a temperature dip to an average of 71.1°F (21.7°C) at night.Heat index
For August, the heat index is estimated at an extremely hot 109.4°F (43°C). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. Remember that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. Make an effort to avoid direct sun exposure during these hours. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
