Bali faces another dry week, with the rainy season expected to arrive unevenly

In brief: BMKG's 20 October outlook points to continued dry weather across much of Bali; November is the earliest broad indication for the seasonal transition, while most of the island's climate zones are forecast to enter the wet season in December.

The latest outlook leaves room for local showers

Aminudin Al Roniri, head of BMKG's Bali climatology station, told detikBali on 20 October that predominantly dry conditions were expected over the coming week and could last until the transition to the rainy season. He linked the heat to limited cloud cover during the dry season and the influence of El Niño.

BMKG's official bulletin for 20–26 October supports that assessment. It includes Bali among the areas where relatively dry conditions could persist from late October into the second ten-day period of November, while allowing for local rain.

The bulletin advises people spending daytime hours outdoors to use sun protection and stay hydrated. It also calls for water conservation; it does not impose water-supply restrictions. BMKG recommends following local forecasts and warnings through its official channels, including the InfoBMKG app, when planning daily activities.

Most climate zones have a December start in the seasonal forecast

The November reference is part of an outlook already published in September. Reporting on the Bali station's seasonal briefing on 28 September, detikBali put the expected start of the rains in November for three of Bali's 20 climate zones and in December for the other 17. Those are counts of zones, not percentages of the island's land area.

BMKG's national announcement on 22 September likewise placed some of Bali in the November group and most of it in December. The 20 October statement adds a current assessment of the dry spell to that seasonal picture. Residents should not plan around an island-wide end to the heat when November begins.
