Clima en Uluwatu, Bali en septiembre

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.

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.
