The Short Answer
For most travelers, the best time to visit Bali is from April to October. That's the dry season. Expect sunny days, low humidity, and calm seas. July and August are the busiest and priciest months. If you want good weather without the peak-season chaos, aim for May, June, or September.
Dry Season (April–October): The Sweet Spot
Temperatures hover around 27–30°C (80–86°F) year-round. But from April to October, rainfall drops dramatically. In June, you'll see just 60mm of rain compared to 300mm in January. The ocean is calm, making it ideal for snorkeling in Amed or surfing in Uluwatu.
May and June are particularly good. Crowds are thinner than July–August, and hotel prices run 20–30% lower. Book flights and stays at least 2–3 months ahead if you're coming in peak season.
Wet Season (November–March): Lower Prices, Lush Views
Yes, it rains. But not all day. Typically, you'll get a heavy downpour in the afternoon, then clearing skies. The upside: rice terraces in Ubud are emerald green, waterfalls are roaring, and hotel rates drop by as much as 40%.
If you're on a budget, this is your window. Just pack a light rain jacket and plan outdoor activities for the morning. November and March are transitional months—still plenty of sunshine, but with more showers.
Festivals and Events: When to Go for Culture
Bali's calendar is packed with ceremonies. Nyepi (Balinese New Year) falls in March—the whole island goes silent for 24 hours. It's a unique experience, but note that the airport closes and you'll need to stay indoors.
Galungan and Kuningan occur every 210 days, usually in spring or autumn. You'll see tall 'penjor' bamboo poles lining the streets. The Ubud Writers & Readers Festival in October is a big draw for literary types. Check the exact dates each year, as they shift with the lunar calendar.
Surfing, Diving, and Hiking: Timing by Activity
Surfers: The dry season (May–September) brings consistent swell to the west coast—think Kuta, Canggu, and Uluwatu. Waves are bigger and cleaner. In the wet season, head to the east coast for smaller, more manageable breaks.
Divers: April–October offers the best visibility, often exceeding 30 meters. For hikers, Mount Batur sunrise treks run year-round, but the dry season gives you clearer views. Avoid the summit during heavy rain in January–February; trails get slippery and views vanish.
Crowds and Costs: Month-by-Month Snapshot
July and August are peak season. Expect crowds at Tanah Lot and Uluwatu Temple, and book everything early. December is also busy, especially around Christmas and New Year.
For a balance of good weather and lighter crowds, try May, June, or September. You'll find 25–30% lower accommodation rates than in July. If you're flexible, October is a hidden gem—still dry, fewer tourists, and prices drop further as the wet season approaches.
Final Tips for Planning Your Trip
No matter when you go, book popular spots like Nusa Penida day trips or cooking classes in Ubud at least a week ahead. In the wet season, choose a hotel with a good pool and indoor lounge—you'll use them.
Check visa rules: many nationalities get 30 days free on arrival. For longer stays, the 60-day tourist visa is easy to arrange online. And always pack reef-safe sunscreen—it's better for the coral and increasingly required at dive sites.
