Strong sunshine expected to push temperatures in Indonesia to 37°C on November 16

Warm air and strong sunshine to raise temperatures

From November 15 to 17, mostly sunny conditions across Indonesia will allow solar radiation to warm the ground, while warm air will also contribute to rising temperatures. Air temperatures of +18°C or higher at around 1,500 m are spreading broadly from the Indian Ocean, continuing to warm areas near the surface. The heat is expected to peak on November 16.

Outlook for affected areas

Strong sunshine and warm air are expected to persist during the period. Surabaya is forecast to reach 37°C between November 15 and 17, with humidity forecast to range from 45% to 58%. On November 18, cloud cover is expected to increase over Surabaya, weakening solar radiation and bringing temperatures down to 34°C. Denpasar is forecast to reach 33–34°C and Jakarta 31–32°C; neither is expected to reach 35°C.

Try to avoid going outdoors during the day as much as possible. Drink fluids regularly and take steps to cope with the heat, such as improving ventilation indoors.
