Weather in October
Temperature
The start of October marks an average high-temperature of a still hot 30.9°C (87.6°F), hardly distinguishable from the conditions in September. Throughout October, the temperature falls to an average low of 21.8°C (71.2°F).Heat index
The heat index value for October is appraised at a blistering 40°C (104°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 of high significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
