Weather in September
Temperature
September brings an average high-temperature of a still hot 86.7°F (30.4°C), showing a slight difference from August's 90.1°F (32.3°C). Malvern's nights in September cool down to an average low-temperature of 69.6°F (20.9°C).Heat index
During September, the heat index is computed to be a very hot 98.6°F (37°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. 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.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Sunshine
The average sunshine in September in Malvern is 8.8h.UV index
In Malvern, the average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for average individuals.Note: The maximum daily UV index of 6 in September interprets into the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
