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 (4.57") 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

The advent of November brings an average high-temperature of a still tropical 31.5°C (88.7°F), almost identical to the preceding month. Jakarta indicates a consistently low-temperature of 26.5°C (79.7°F) during the nights of November.

Heat index

November's mean heat index is calculated to be a very hot 39°C (102.2°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Humidity

The average relative humidity in November is 70%.

Rainfall

The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.
Note: The maximum UV index, 7 during November, leads to the following recommendations:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
