November weather forecast
Jakarta, Indonesia

As November rolls in, Jakarta's weather transitions fully into the wet season. This month records substantial rainfall, up to 116mm thereby indicating the progression into the city's rainy period. The increase in precipitation does not bring about a major shift in other weather parameters such as temperature, UV index, and sea temperature. The number of rainy days increases significantly compared to October, and the cloud coverage increases to 37%. Despite the resurgence of the rainy season, November provides ample sunshine, making it versatile for both indoor and outdoor activities.

Temperature

With the start of November, Jakarta measures an average high-temperature of a still tropical 31.5°C, not significantly differing from October's 31.8°C. November introduces a small decrease to a nighttime average of 26.5°C.

Heat index

The heat index value for November is estimated at a torrid 39°C. Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In November, the average relative humidity is 70%.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
