Weather in October
Temperature
The arrival of October brings an average high-temperature of a still tropical 30.2°C (86.4°F), closely following the temperature pattern of September. Throughout October, the average low-temperature records at a warm 24.2°C (75.6°F).Heat index
October's heat index is calculated to be a very hot 38°C (100.4°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Take note of the fact that heat index values are based on shaded circumstances with light airflows. 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 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. 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. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
