Weather in October
Temperature
As Chapa transitions into October, a marginal rise in the average high-temperature is observed, moving from a tropical 31.6°C (88.9°F) in September to a still hot 34.9°C (94.8°F). During October nights, Chapa records an average temperature of 23.6°C (74.5°F).Heat index
The heat index value during October is estimated at a life-threatening hot 52°C (125.6°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
