Bali Weather Guide

Bali has a tropical monsoon climate with two distinct seasons. The dry season runs from approximately April to October, driven by southeasterly trade winds from Australia. The wet season runs from November to March, when moisture-laden winds from the northwest bring heavy afternoon and evening rains.

Temperatures are warm and humid year-round, ranging from a comfortable 25°C in the early morning to 33°C in the afternoon heat of the dry season. Bali's central volcanic mountains — including Gunung Agung (3,031m) and Gunung Batur — create a microclimate: Ubud and the highlands receive more rainfall and are notably cooler (20–27°C) than the southern beach areas year-round.

Sea temperatures around Bali stay between 27°C and 30°C throughout the year, making swimming and snorkelling comfortable in every month. Ocean conditions — particularly for surfing — change dramatically between seasons due to swell direction and wind patterns.

The dry season is the prime time to visit Bali for most travellers. From April onwards, rainfall decreases dramatically, skies are clear, and the southeast trade winds keep the air fresh rather than stifling. Surfing conditions peak during this period as south and southwest swells roll in and offshore winds groom the waves at Uluwatu, Padang Padang, and Canggu.

July and August are the absolute peak tourist months — Australian school holidays, European summer break, and Japanese summer holidays converge to create Bali's most crowded and expensive period. Accommodation prices can be 30–100% higher than shoulder season, and popular spots like Tegallalang Rice Terrace, Tanah Lot, and Uluwatu Temple are genuinely crowded from mid-morning.

May, June, and September are the sweet spot of the dry season. Weather is reliable and beautiful, the tourist crowds are noticeably thinner, and accommodation prices are significantly lower than peak. These three months represent the best value-to-weather ratio in Bali's calendar. Early October is also excellent — the dry season lingers, locals celebrate Galungan and Kuningan (major Balinese Hindu festivals), and the island feels festive.

The dry season is also when Bali's ceremonial and cultural calendar is most vibrant. Nyepi (Day of Silence) falls in March or April (Hindu New Year on the Saka calendar) and is Bali's most unique cultural experience — the island goes completely dark and silent for 24 hours, with no traffic, lights, or noise permitted.

November through March is Bali's wet season. Rain typically falls in heavy afternoon or evening downpours lasting 1–3 hours, with mornings often clear and beautiful. This pattern makes wet season Bali very liveable — mornings for outdoor activities, afternoons for temples, cooking classes, or spa sessions, and evenings after the rain for dining.

December and January are the wettest months. The landscape transforms: rice terraces become vivid emerald green, waterfalls run at full force (Sekumpul, Gitgit, Nungnung are spectacular), and jungle interiors feel lush and alive. For photographers and nature lovers, wet season Bali has a beauty that the dry season can't match.

Surf conditions change significantly in the wet season. The main south-facing breaks (Uluwatu, Kuta, Padang Padang) see onshore winds making conditions messier. However, the north and east coasts (Amed, Lovina, Nusa Dua's east side) can have excellent conditions during wet season swells.

The wet season is by far the cheapest time to visit Bali. Hotel rates drop 20–40% from July–August peaks. Restaurants and attractions are less crowded. For budget travellers, cultural explorers, and those who don't mind occasional rain, December–February can be a genuinely rewarding time to visit — just pack a light rain jacket.

January: Wettest month. Lush landscapes, lowest prices, fewest tourists. Rain mostly afternoons. Good for cultural tourism.

February: Still wet but improving. Nyepi preparations begin. Water temples are active. Good value.

March: Transition month. Rain decreasing. Nyepi (Day of Silence) typically falls in March or April — a uniquely Balinese experience.

April: Dry season beginning. Conditions improving rapidly. Excellent time to visit — good weather, pre-peak prices.

May: Outstanding. Full dry season, fewer crowds than July–August, beautiful conditions for beaches, hiking, and temples.

June: Excellent. Similar to May. Surf season hitting its stride. Shoulder rates still apply in early June.

July–August: Peak season. Best weather, biggest crowds, highest prices. Book accommodation 3–6 months ahead.

September: One of the best months. Dry season continues, crowds thin as European and Australian summer ends. Excellent value.

October: Very good. Dry season lingering. Galungan festival (if it falls this year) adds cultural richness. First rains possible late October.

November: Wet season beginning. Prices dropping. Still many clear mornings. Good for budget travellers.

December: Wet and festive. Christmas and New Year bring a surge of Australian tourists (December is their summer). Prices spike for peak Christmas–New Year week.
