Weather in August
Temperature
With the advent of August, Grimstead experiences an average high-temperature of a moderately hot 85.6°F (29.8°C), mirroring a close resemblance to the previous month. An average low-temperature of 71.2°F (21.8°C) is common during the nights of August.Heat index
In August, the average heat index is estimated at a very hot 95°F (35°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild 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 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 especially vital to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
