Weather in October
Temperature
October's presence marks an average high-temperature of a still warm 29.4°C (84.9°F), subtly varied from September's 29.5°C (85.1°F). Haliyadda experiences an average temperature drop to a pleasant 20.7°C (69.3°F) during October nights.Heat index
During October, the heat index is calculated to be a torrid 36°C (96.8°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
