מזג האוויר בJimbaran (Bali) ביולי

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.

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.
