Het weer in Uluwatu, Bali, Indonesia in 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.

Uluwatu-forum and surf-guide threads on July agree it's the peak of the low-rain season and the peak of the swell: the year's biggest groundswells arrive this month, reliable SE trade winds blow offshore into the Bukit Peninsula's west-facing breaks every morning, and rainfall runs among its lowest totals of the year. The trade-off is crowding - the lineup itself is described as resembling a small city by mid-month, though most surfers call the wave quality worth it. Wind is the other consistent theme: mornings run clean and glassy, but afternoons turn genuinely blustery, choppy enough to affect snorkeling and noticeable enough that clifftop restaurant tables catch a steady breeze through the evening. Warm, sunny days are the norm. The record: 27.4C days, 24.5C nights, 57mm across 18 days, a 27.6C sea, 73 percent humidity and 10.9 hours of sun - more scattered rain days than the guides' "minimal rainfall" framing suggests.
