Weather in August
Temperature
The transition into August reveals an average high-temperature of a still tropical 89.2°F (31.8°C), mirroring a close resemblance to July. Throughout the August nights, Chelsea encounters a low-temperature of 69.1°F (20.6°C).Heat index
For most parts of August, the heat index is estimated at a blistering 104°F (40°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Observations indicate that the heat index values are for shady locations with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. As body temperatures escalate without effective heat release, one might face dehydration threats.
