Peak Season: June to September; December These months see sunshine, low humidity, and surf-friendly western shore winds. The downside to this period are the many travelers who arrive en masse (August, September, and the December holidays are the busiest). Expect premium rates.
Off Season: January to March These months are the hottest, with high humidity and almost daily tropical downpours. The Japanese traditionally descend in droves for Golden Week vacation during February; otherwise, hotels and villas can be had at a discount.
Sweet Spot: April to May; November These months, on the tail ends of the rainy season, typically see nice weather, fewer crowds and attractive discounts throughout Bali.
