When to Visit Bali: Best Time & Monthly Weather Guide

Bali sits just 8 degrees south of the equator, which means temperatures stay locked in a narrow band — 26–28°C (79–82°F) all year — but rainfall swings dramatically between seasons. The island divides its year into a wet season (November through March) and a dry season (April through October), and that divide is the single most important factor in planning your trip. The clearest, driest, most comfortable months are June through September, with August standing out as the statistical peak: just 18 mm of rain, 9 hours of sunshine per day, and humidity at its annual low of 72%. What changes the feel of any given month is not temperature but that humidity — and knowing when it drops makes all the difference. This guide covers every month, packing essentials, weather-aware tips, and the FAQs travelers search most before booking a flight.

Best Time to Visit Bali

The Sweet Spot: June to September

Bali's dry season runs from roughly April to October, but the months of June, July, August, and September consistently offer the best combination of low rainfall, manageable humidity, and reliable sunshine. August is the statistical high point: only 18 mm of rain for the entire month, 9 hours of sunshine per day, and humidity dropping to 72% — low by Balinese standards. September follows closely with just 47 mm of rain and 8 hours of sun.

July and August are also Bali's peak tourist months, which means crowds at Seminyak and Ubud, higher villa rates, and flights that book out weeks in advance. If you want dry-season conditions without peak-season pricing, June is the smart move — rainfall averages 53 mm, sunshine holds at 8 hours a day, and accommodation rates are noticeably softer than in July or August.

Shoulder Seasons: April–May and October

April and May are genuinely underrated. Rainfall drops sharply from the March wet-season tail (234 mm in March versus 88 mm in April), temperatures nudge up to 28°C, and tourist infrastructure is fully operational. October sees rain beginning to build again (63 mm) but remains comfortable, with 8 hours of sun and humidity around 77%.

What to Avoid

January is Bali's wettest month on record, averaging 345 mm of rain — nearly 20 times August's total. December is the second worst at 276 mm. Heavy daily downpours during these months cause flooding on coastal roads, close surf breaks to swimmers due to runoff, and reduce visibility on the water. If your itinerary is centered on beaches, snorkeling, or outdoor hiking, January and December carry real trade-offs. Budget travelers and surfers who know the breaks can find value in this window, but go in with clear expectations.

Climate Overview

Tropical Monsoon Climate

Bali has a classic tropical monsoon (Am) climate, driven by the reversal of monsoon winds across the Indonesian archipelago. The northwest monsoon brings moisture-laden air from the Indian Ocean between November and March, producing the wet season. The southeast trade winds dominate from May through September, pulling drier air across the island and creating the conditions that make Bali so appealing for beach tourism.

Temperatures are remarkably stable. The annual average is 26.9°C, and the range between the warmest months (April and November, both 28°C) and the coolest (June, July, August — all 26°C) is just 2 degrees. What changes the feel of Bali's heat is humidity: January sits at 85%, while August drops to 72%. That 13-point swing is the difference between oppressive afternoon air and a genuine sea breeze.

Sunshine hours follow the rainfall pattern in reverse. August peaks at 9 hours per day; January, February, and December each manage only 6. The annual average of 7.4 hours per day is generous, but heavy cloud cover can dominate wet-season afternoons.

Elevation and Micro-Climates

Bali's interior rises above 3,000 metres at Gunung Agung. The highlands around Ubud (roughly 300 m) and Kintamani (1,500 m) are cooler and wetter year-round than the coast. Pack a light layer for any highland excursion, even in the dry season.

Month-by-Month: What to Expect in Bali

January

Bali's wettest month averages 345 mm of rain and just 6 hours of sunshine; humidity sits at 85%. Mornings are often usable before afternoon downpours arrive. Best for surfers chasing northwest-swell breaks at Canggu and budget travelers willing to trade dry skies for discounted villa rates.

February

Rainfall eases to 274 mm but conditions remain heavy, with 85% humidity and 6 hours of sun. Galungan — the 10-day Hindu festival marking the victory of dharma — often falls in February, filling roadsides with bamboo penjor poles and temple offerings. A culturally rewarding month despite the weather.

March

The wet season starts to retreat: 234 mm of rain and 7 hours of sunshine. Nyepi (Day of Silence) typically falls in March, shutting the entire island down for 24 hours — no vehicles, no lights, no flights. Plan your travel dates carefully, or treat it as a rare experience.

April

April is the turning point. Rainfall drops to 88 mm, temperatures climb to 28°C, and 8 hours of sunshine return daily. Humidity eases to 80%. Excellent value for first-time visitors: dry-season conditions at shoulder-season prices.

May

With 93 mm of rain, 8 hours of sun, and humidity at 78%, May is a quietly strong month. Surf conditions improve on south-facing Bukit Peninsula breaks, and dive visibility around Tulamben and Amed picks up as seas calm. Shoulder pricing holds throughout.

June

The dry season proper begins: 53 mm of rain, 75% humidity, 26°C. Clear pre-dawn skies make June the most reliable window for the Gunung Batur summit hike. Accommodation rates start rising mid-month as Australian and European school holidays approach.

July

Peak season. At 55 mm of rain, 73% humidity, and 8 hours of sun, the weather is excellent — as is the crowd. Seminyak villas sell out weeks ahead and flight prices spike. Book at least six weeks in advance.

August

Statistically Bali's best month: 18 mm of rain, 9 hours of sunshine, and humidity at its annual low of 72%. Temperatures sit at 26°C with a reliable southeast trade wind. Kitesurfers thrive at Nusa Dua; expect peak pricing across all accommodation categories.

September

Nearly identical to August — 47 mm of rain, 8 hours of sun, 74% humidity — but with noticeably thinner crowds as school holidays end. Prices begin sliding back toward shoulder levels. For travelers with flexible schedules, September is often the best overall value in the dry season.

October

Rainfall ticks up to 63 mm and humidity returns to 77%, but 8 hours of sunshine persist. Rice terraces at Tegalalang and Jatiluwih are lush without being flooded. Diving at Menjangan Island remains excellent through the month.

November

The northwest monsoon re-establishes with 179 mm of rain, humidity at 82%, and temperatures reaching 28°C. Afternoon storms intensify through the month. The Saraswati festival, celebrating the arts and knowledge, typically falls here and is worth planning around.

December

At 276 mm of rain and 84% humidity, December mirrors January's conditions. Christmas and New Year drive a major tourist surge, pushing prices to their annual peak in the final two weeks. The beach-club scene is undimmed by rain; travelers focused on outdoor activities will find far better conditions in April.

What to Pack for Bali

Dry Season (June–October)

Light, breathable fabrics are non-negotiable year-round, but the dry season lets you travel light. Linen or bamboo-blend shirts and shorts outperform synthetic fabrics in Bali's humidity. A reef-safe sunscreen (SPF 50+) is essential — the equatorial UV index regularly hits 11–12. Add a wide-brimmed sun hat and UV-blocking sunglasses for midday temple visits and rice-terrace walks. The southeast trade winds in August can make Jimbaran Bay evenings cooler than expected; a light cotton layer handles it.

Wet Season (November–May)

A packable rain shell beats an umbrella — motorbike taxis make umbrellas impractical on the move. Quick-dry sandals that handle getting soaked are worth prioritizing over leather footwear. A dry bag or waterproof phone case protects electronics during scooter rides in rain.

Cultural Dress Codes

Every Hindu temple requires visitors to wear a sarong and sash — available for rent at entrances, but bringing your own lightweight cotton sarong is more hygienic and avoids queues. Shoulders should be covered at temples and cremation ceremonies. At Tanah Lot and Besakih, dress codes are enforced regardless of the season.

Practical Tips for Travelers

• Book summit hikes well ahead. The pre-dawn climb to Gunung Batur (1,717 m) requires a licensed guide, and popular operators sell out weeks in advance in July and August. June is the earliest reliably clear month — wet-season summit clouds frequently obscure the view.
• Front-load outdoor activities. Across all months, mornings are statistically clearer than afternoons. Snorkeling, cycling, and rice-terrace walks are best before noon; save temple visits and cooking classes for the post-rain afternoon hours.
• The airport road floods. The coastal bypass connecting Ngurah Rai Airport to Seminyak sits at near sea level. After heavy January or February storms, a 30-minute transfer can stretch to two hours. Consider staying near the airport precinct the night before an early-morning wet-season flight.
• Humidity accelerates mold. In wet-season accommodation below mid-range, leather goods, cameras, and paper documents stored in closed bags can develop mold within days. Keep camera bags open or use silica gel packs — widely available at local hardware stores for around IDR 5,000.
• Negotiate villa rates in January–February. Private villa occupancy in Seminyak and Canggu routinely drops below 30% in peak wet season. Direct inquiries to villa managers — bypassing booking platforms — frequently yield 20–35% off published rates for stays of five nights or more.
• Dry-season winds create beach hazards. August winds along the Sanur and Nusa Dua coastlines bring out kitesurfers in numbers. Designated swim zones exist but are not always respected — scan the water before wading in.

Frequently Asked Questions

What is the rainy season in Bali?

Bali's rainy season typically runs from November through March, with the heaviest rainfall in January (345 mm on average) and December (276 mm). Rain usually falls in intense afternoon downpours rather than all-day drizzle, so mornings often remain usable. April marks a significant improvement, with rainfall dropping to around 88 mm.

Is Bali too hot to visit in the wet season?

Temperatures in Bali barely shift year-round — the range is just 26–28°C. The discomfort in the wet season comes from humidity (85% in January and February) rather than heat alone. Combined with 27°C temperatures, that humidity produces a feels-like temperature well above 30°C and makes sustained outdoor activity tiring. The dry season's 72–75% humidity is noticeably more comfortable for the same temperature.

When is Bali least crowded?

The quietest periods are January through March and, to a lesser extent, May and early June. January and February offer the lowest accommodation rates of the year but come with the heaviest rainfall. May is arguably the best low-crowd window with genuinely good weather — 93 mm of rainfall and 8 hours of sunshine per day.

Is August always sunny in Bali?

August is statistically Bali's sunniest and driest month — 9 hours of sunshine per day and only 18 mm of average rainfall — but no tropical destination guarantees perfect weather. Occasional passing showers can still occur, and the southeast trade winds bring overcast mornings on some days. In most years, however, August delivers sustained clear conditions with reliable afternoon sea breezes.

Can you still surf Bali in the dry season?

The dry season (June–October) is excellent for the south-facing breaks on the Bukit Peninsula — Uluwatu, Padang Padang, and Bingin are at their most consistent. The wet season produces larger swells for west-coast breaks at Canggu and Medewi, where northwest swells are more frequent between December and March. Experienced surfers often prefer the wet season for wave quality despite the conditions.

Final Word

Bali's weather tells a clear story: visit between June and September for the driest, sunniest, and most comfortable conditions, with August delivering the statistical peak and September offering nearly identical weather with smaller crowds. April and May reward travelers willing to accept occasional showers with good conditions and shoulder-season prices. Avoid January and December if outdoor activities are central to your trip.
