Warm air expected to bring temperatures to 35°C in Surabaya, Indonesia

Warm air and strong sunlight to raise temperatures

From October 4 to October 8, temperatures are expected to rise in Indonesia as warm air combines with strong sunlight. Warm air of +18°C or higher is spreading widely from the Indian Ocean at around 1,500 m above ground, continuing to warm areas near the surface. With few clouds, the effects of sunlight are also contributing, and these conditions are expected to continue.
