Weather in August

August, the last month of the summer in Rugby, is another warm month, with an average temperature ranging between min 63.3°F (17.4°C) and max 84.7°F (29.3°C).

Temperature

Rugby signifies an average high-temperature of a still warm 84.7°F (29.3°C) in August, closely mirroring the 85.6°F (29.8°C) of July. Rugby's nighttime temperature in August drops to an average of 63.3°F (17.4°C).

Heat index

The heat index for August is appraised at a torrid 95°F (35°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Consider that heat index readings are for situations in the shade and light wind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
