Thinking of visiting Nusa Lembongan? One of the most common questions we hear is, "When's the best time to come?" The short answer? Almost any time of year.
Like the rest of Bali, Nusa Lembongan has two distinct seasons rather than four. While you'll often hear people talk about the "wet season" and "dry season", the reality is much more relaxed than those names suggest.
If you're picturing endless days of rain, muddy streets and cancelled holidays... don't worry. That's rarely what happens here.
Dry Season (April to October)
This is considered peak season, and for good reason.
During these months you'll usually enjoy:
- Warm sunny days
- Low humidity
- Crystal clear water
- Excellent snorkelling visibility
- Consistent surf
- Cooler evenings
Average daytime temperatures sit between 27°C and 31°C, while evenings can feel surprisingly comfortable thanks to the ocean breeze.
This is also when the island is at its busiest, especially during July, August and school holidays.
Wet Season (November to March)
Here's the biggest misconception...
The wet season doesn't usually mean it rains all day.
More often than not, you'll wake up to sunshine, enjoy a beautiful morning, experience a heavy tropical shower for 20 to 60 minutes in the afternoon, then finish the day with another spectacular sunset.
Some days are completely dry.
Other days bring dramatic thunderstorms that pass almost as quickly as they arrive.
In fact, many locals actually love this time of year.
The island feels greener, accommodation prices are often lower, and popular beaches are noticeably quieter.
Sea Conditions
Sea Conditions & The Sanur–Lembongan Crossing
The ocean around Nusa Lembongan changes throughout the year, and conditions can vary from beautifully calm to a little more adventurous depending on the season, wind, swell and weather.
If you’re worried about the fast boat crossing from Sanur to Nusa Lembongan, it’s worth remembering that a bumpy crossing doesn’t necessarily mean an unsafe crossing. Fast boat operators make this journey every day and monitor sea and weather conditions closely. When conditions are unsuitable, services may be delayed, rescheduled or cancelled rather than operating as normal.
The crossing itself is relatively short, generally around 30–45 minutes, depending on the boat, departure point and sea conditions. On calm days it can be remarkably smooth. When there is wind or swell, you may experience more movement, spray and a bumpier ride, particularly as the boat leaves Sanur or approaches Lembongan.
During the dry season, conditions around the islands are often favourable for snorkelling and diving, although larger ocean swells can still occur. During the wet season, changing winds and weather systems can affect visibility and sea conditions. Local snorkelling and diving operators monitor this daily and adjust sites accordingly, choosing locations that offer the best conditions available.
If rough weather is forecast and you’re a nervous traveller, give yourself some flexibility. Check with your fast boat operator before departure, consider travelling earlier in the day when appropriate, and allow some breathing room in your itinerary rather than booking an important international flight immediately after your return crossing.
And if the forecast looks dramatic on your weather app, don’t panic. Rain on Nusa Lembongan does not automatically mean dangerous seas, and a rough-looking ocean does not automatically mean boats aren’t operating. Local conditions matter, and your boat operator is the best source of information about whether your particular crossing is going ahead, if conditions are not safe, the harbour will be closed.
The ocean is part of island life. Some days it’s glassy, some days it has a bit more personality. The important thing is to travel with a reputable operator, follow their advice and allow a little flexibility when Mother Nature decides she’s running the timetable.

That's island life.
And honestly? We wouldn't have it any other way.
Island Pulse Tip
Don't let the weather forecast scare you.
Many forecasting apps show rain icons for an entire day, even if the island only receives one short tropical shower. We've lost count of how many visitors have expected a washout, only to spend most of the day swimming, exploring and soaking up the sunshine.
Pack your swimmers, a light rain jacket, and a sense of adventure.
