DenpasarBali is set for mostly clear to partly cloudy weather on 21 September, with the provincial weather office forecasting generally stable conditions across the island, according to the national meteorology agency and local reporting. The forecast shows temperatures around 20-32 C, with humidity remaining high in many areas.

For Denpasar, Badung and Jembrana, the forecast points to clear to partly cloudy skies, while Bangli, Gianyar, Karangasem and Tabanan are expected to be more cloudy at times. Buleleng and Klungkung are also forecast to see mostly fair weather, with no widespread rain expected for the day, according to the agency’s Bali forecast and local media summaries of the same data.

The meteorology agency’s Bali forecast also shows humidity ranging from about 58 percent to 99 percent across the island, depending on location. That combination of warm temperatures and high moisture is typical for Bali’s transition toward wetter conditions, although the day itself is still expected to remain largely dry.

Local reports also said there is no rain warning for Bali’s regencies and cities during the forecast period from 21 September to 22 September. Marine forecasts, however, indicate higher waves in southern waters around Bali, including the southern Bali sea and nearby straits, which remain relevant for boat operators and coastal activity.

Travellers and residents planning outdoor activities should still keep an eye on short-term updates, especially along the coast and at sea. While the land forecast is broadly calm, the marine outlook points to rougher conditions in southern waters than on land.
