When Is the Best Time to Visit Nusa Lembongan? A Month-by-Month Weather Guide
The best time to visit Nusa Lembongan is from April to October, during the dry season, when sunny days, generally calmer seas and good underwater visibility create ideal conditions for beach holidays, snorkelling, diving and surfing. July and August are the busiest months, while September is an excellent choice for travellers seeking warm, dry weather with fewer crowds.
Off Bali’s south-east coast, Nusa Lembongan offers a relaxed island atmosphere, beautiful beaches, and easy access to some of Indonesia’s most memorable marine experiences. However, the best time to visit depends on your priorities, whether you want consistent surf, opportunities to see manta rays, a peaceful family holiday or better accommodation rates.
Understanding the weather, seasonal marine life and visitor numbers will help you choose the right time for your stay. This guide explains Nusa Lembongan weather by month, the differences between the dry and rainy seasons, and how to plan a comfortable island escape at Lembongan Island Beach Villas.
What Is the Best Month to Visit Nusa Lembongan?
September is one of the best months to visit Nusa Lembongan because it combines dry weather, warm temperatures, generally favourable sea conditions and fewer visitors than the July and August peak season. April to June is another excellent period, particularly for travellers who prefer a quieter island experience as the dry season begins.
For most visitors, April to October offers the best overall balance of sunshine and outdoor activities. Nevertheless, each period has its advantages.
Best overall weather: July to September, during the established dry season.
Best for fewer crowds: April to June and September to October.
Best for surfing: Generally April to September, when south-west swells are more consistent.
Best for manta rays: March to November is a broad window suggested by local operators, although sightings are never guaranteed.
Best chance of seeing sunfish (mola mola): June to October, depending on ocean conditions and local sightings.
Best for a quieter, potentially more affordable stay: November to March, excluding the busy Christmas and New Year period.
These are seasonal guidelines rather than guarantees. Weather, swell, currents, and wildlife sightings vary from year to year.
Nusa Lembongan Weather by Season
Nusa Lembongan has two main seasons: the dry season, which runs approximately from April to October, and the wetter season, which generally lasts from November to March. Unlike Bali’s mountainous interior, the island is often relatively dry, though tropical showers and humid days are possible year-round.
April to June: The Dry Season Begins
April to June is an appealing time to visit Nusa Lembongan as rainfall generally decreases and the weather becomes more consistently suitable for outdoor activities.
The island starts to experience longer periods of sunshine, making this season ideal for beach walks, exploring coastal viewpoints, snorkelling and enjoying time by the pool. Surf conditions can also improve as Indian Ocean swells become more consistent.
Visitor numbers are usually more moderate than in July and August, although public holidays and school holidays can still influence demand.
Best for: Couples, families, surfers and travellers who want a balance of favourable weather and a more relaxed atmosphere.
July to August: Peak Season for Sunshine and Surf
July and August are among the most popular months to visit Nusa Lembongan. Dry weather, abundant sunshine and consistent surf attract visitors from Australia, Europe and other international markets.
These months are particularly suitable for travellers planning beach days, diving trips and boat excursions. Depending on ocean conditions, they can also offer opportunities to encounter manta rays and the elusive sunfish around nearby dive sites.
The main consideration is demand. Accommodation can book out well in advance, and popular restaurants, surf breaks and island excursions may feel busier than during the shoulder season.
Best for: Travellers prioritising dry weather, surfers, diving enthusiasts and visitors travelling during the Australian or European summer holidays.
Planning tip: Book accommodation and key activities early if you plan to visit in July or August.
September to October: Sunshine Without the Peak Crowds
September is often one of the most attractive months for a Nusa Lembongan holiday. The dry season generally continues, while visitor numbers often ease after the July and August rush.
Sea conditions can remain favourable for snorkelling, diving and boat trips, although conditions always depend on the day. September and October can also provide good opportunities for travellers hoping to explore the island at a more relaxed pace.
October marks the transition to the wetter season. Rainfall may increase towards the end of the month, so it is sensible to keep some flexibility in your plans.
Best for: Couples, families, divers and travellers looking for warm weather, quieter beaches and a more peaceful island stay.
For guests seeking a private villa experience, September is particularly worth considering because it combines the appeal of the dry season with a potential reduction in peak-season demand.
November to March: The Rainy Season
The rainy season on Nusa Lembongan typically runs from November to March, with January and February usually experiencing the heaviest rainfall.
Rain does not necessarily mean continuous wet weather. Tropical showers can pass relatively quickly, leaving time to swim, dine, relax by the pool, or explore the island between showers.
However, this period can bring rougher sea conditions and less predictable boat crossings between Sanur and Nusa Lembongan. Outdoor activities may need to be rearranged, particularly when wind, swell or strong currents affect marine excursions.
Accommodation rates may be more attractive during quieter weeks, although demand increases around Christmas and New Year.
Best for: Travellers seeking a slower-paced holiday, flexible itineraries and potential accommodation savings.
Planning tip: Allow flexibility in your schedule and avoid booking essential onward travel too close to your return boat crossing.
Nusa Lembongan Weather and Crowds at a Glance
These periods describe typical seasonal patterns, not a daily forecast. Check local weather and sea conditions before travelling or booking ocean activities.
Best Time to Visit Nusa Lembongan for Marine Life
Nusa Lembongan is known for its clear-water snorkelling sites, colourful reefs, manta rays and access to dive sites around neighbouring Nusa Penida. The right season can improve your chances of enjoying these experiences, although marine wildlife never follows a guaranteed schedule.
Manta Rays: March to November
You can encounter manta rays around Nusa Penida and Nusa Lembongan throughout much of the year. Local operators often suggest March to November as a good window for visiting Manta Bay, but sightings depend on currents, water conditions, and the animals’ movements.
Choose a reputable operator that follows responsible wildlife-viewing practices, maintains appropriate distances and prioritises safety.
Sunfish (Mola Mola): June to October
The cooler-water season around Nusa Penida can bring opportunities to see ocean sunfish, also known as mola mola. Dive operators often recommend June to October, particularly for experienced divers visiting suitable sites.
Sightings remain unpredictable, and not every dive will encounter one. Water temperature, currents and dive-site conditions should determine whether an excursion is appropriate.
Snorkelling and Diving: April to October
The dry season is generally a strong choice for snorkelling and diving because conditions can be more favourable for boat access and underwater visibility. September is particularly appealing for travellers hoping to combine marine activities with a quieter holiday.
Even during the dry season, currents around Nusa Penida can be powerful. Always follow your guide’s advice and select activities that match your swimming ability and experience.
Best Time to Visit Nusa Lembongan for Surfing
The most consistent surf conditions generally occur during the dry season, particularly from April to September, when south-west swells reach the island’s established breaks.
Surf spots around Nusa Lembongan offer different conditions depending on swell direction, tide and wind. Some breaks suit experienced surfers, while beginners may benefit from lessons and carefully selected conditions.
The wet season can still produce rideable waves, but wind and weather may make conditions less predictable.
If surfing is your main reason for visiting, plan around the forecast rather than relying on seasonal averages alone. Check local surf reports, ask experienced instructors for advice and avoid entering unfamiliar breaks without understanding the currents and reef conditions.
When Is the Best Time for a Villa Holiday on Nusa Lembongan?
The ideal time for a villa holiday depends on whether you prioritise sunshine, privacy, availability or value.
For travellers who want the most reliable dry-season conditions, July to September is a strong choice. For a balance of good weather and a quieter atmosphere, April to June and September to October may be more appealing.
During the wetter months, a private villa offers a comfortable base for a slower-paced holiday, with time to relax between showers and enjoy time together away from busier tourist areas.
At Lembongan Island Beach Villas, you can explore accommodation options suited to an island escape. Browse our villas to find one that suits your group, travel dates, and preferred style of stay.
With only ten villas, availability can be limited during popular travel periods. Booking around 90 days ahead is a sensible starting point for July and August, while travellers visiting over Christmas, New Year or major holiday periods should consider booking earlier.

Important Planning Tips Before You Visit
A little preparation can help you make the most of your time on the island, whatever the season.
Plan around the boat crossing. Crossings from Sanur can get bumpy during unsettled weather. Follow your boat operator’s instructions and leave a suitable buffer before flights or onward travel.
Schedule ocean activities in the morning where possible. Sea conditions can be more favourable earlier in the day, although this is not guaranteed. Check the local forecast and operator advice.
Check local cultural dates. Nyepi Laut, the Balinese sea day of silence observed around Nusa Lembongan and neighbouring islands, involves restrictions on ocean activities for 24 hours. Its date changes each year, so confirm the arrangements for the relevant year before booking excursions.
Pack for tropical weather. Lightweight clothing, sun protection, swimwear and a reusable water bottle are useful year-round. During the rainy season, bring a light rain jacket and footwear suitable for wet surfaces.
Keep your itinerary flexible. Weather, sea conditions and wildlife activity can change quickly. Avoid scheduling activities back-to-back, especially during the wetter months.
Reserve your villa early. Peak-season demand can limit accommodation options, especially at properties with a small number of villas.
