Weather in October
Temperature
Entering October, Nilaveli's average high-temperature reads a still hot 32.7°C (90.9°F), indicating a close resemblance to the previous month's climate. Nilaveli experiences a nighttime temperature average of 23.2°C (73.8°F) during October.Heat index
For October, the heat index is appraised at a burning hot 45°C (113°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
