Väder i Jimbaran (Bali) i december

Bali-forum threads on December weather (Canggu specifically flagged in beach-condition threads) are consistent that the wet season is genuinely underway, but outcomes vary wildly by trip: one detailed account logged just about two hours of rain total across three weeks spanning mid-December into early January, surfing and swimming at Canggu and nearby beaches without any real weather problem. Other posters describe a more typical wet-season stretch of downpours and cloudy stretches. Bali's microclimates mean a rainy day in Ubud can be a clear one in Canggu or Sanur, so conditions genuinely differ block to block. The recurring practical warning: wet-season currents wash rubbish onto some beaches, worth checking locally. Crowds and traffic climb steadily from mid-December regardless of the weather. The record: 30.9C days feeling like a punishing 37C, 25.3C nights, a notably high 270mm across 28 days, 86 percent humidity, a 29.8C sea and 9.7 hours of sun.

Bali forum threads are consistent that January sits in the heart of wet season - generally the wettest or second-wettest month of the year - with a typical day running sunny, then rain arriving late afternoon into the evening or overnight. Posters were candid that some years bring a genuine 3-4 day stretch of near-continuous rain, though the more common pattern is afternoon showers bookending mostly dry, hot, steamy daytime hours. One west-coast-specific detail worth knowing: during wet season, ocean debris washes down the Java Sea and can wash up on Bali's west-facing beaches including the Jimbaran/Kuta/Seminyak stretch, more noticeably than during the dry months.

Forum posters describe September as genuinely good and mostly dry across Bali, with any rain typically arriving in the early evening or at night (commonly cited as starting around 3:30pm on a rainy day) rather than disrupting daytime plans. Temperatures stay comfortable, neither too hot nor cool. Posters consistently flag Bali's real microclimate variation - it can be raining in one spot while completely dry a mile away, with inland areas (Ubud and similar) generally wetter than the south coast where Jimbaran sits, one of the island's more reliably dry spots. The clear trade-off for the good September weather: this falls within Bali's July-September peak season, further boosted by Australian school holidays, so posters note it's also one of the more crowded times to visit.
