October weather forecast
Jerudong, Brunei

Weather patterns in October remain quite similar to September. However, a notable surge in the rainfall volume, reaching 177mm (6.97"), defines the major change in October’s weather. High temperatures demonstrate a mild decline, but the shift is barely noticeable. Persistent cloudy conditions slightly reduce the overall visibility. Despite the changes, the weather remains bearable with smooth winds blowing, maintaining the breeze.

Heat index

The heat index for October is calculated to be a fiery hot 38°C (100.4°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The average relative humidity in October is 76%.

Note: In October, the maximum UV index of 7 translates into these guidelines:
Take precautions against overexposure. Protection against sun damage is needed. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
