Komodo's weather follows a clear dry and wet season pattern: dry, calmer conditions roughly May to October, with the wet season and rougher, less predictable seas the rest of the year. Within the dry season, the middle months tend to be windier and driest, while the edges of the season carry slightly more chance of a shower and gentler seas. Komodo weather is shaped by two monsoons, and knowing which one is blowing tells you most of what you need.
Our charter fleet sails in Komodo only during the dry season, so this guide focuses on what to expect May through October.
Early dry season: May and June
Coming off the wet season, these months can still bring the odd shower, but seas are already calming and the landscape has not yet dried to its golden peak. Visibility underwater tends to be improving through this period. It is a reasonable choice if you want dry-season conditions without the busiest weeks.
Peak dry season: July to September
This is the driest and often the windiest stretch, particularly around July and August when the southeast monsoon is strongest. Stronger wind can mean livelier seas in exposed channels, which is also what drives the currents that bring manta rays and big fish to the park's better-known cleaning stations. Rain is unusual. The hills across the park are at their most golden and dry.
Late dry season: October
Winds typically ease from the July to August peak, seas tend to settle, and the season is usually still reliably dry. This is also when our fleet begins repositioning towards Raja Ampat for its own season, so it is one of the last windows for a Komodo charter until the following May. See our best time to visit Komodo guide for how this compares across the whole season.
Temperature and humidity
Indonesia sits close to the equator, so temperatures stay warm and fairly consistent through the dry season, with humidity generally lower than in the wet months. Days on the water usually feel more comfortable than the same heat would on land, thanks to the sea breeze, though the sun is strong year round and shade on deck matters more than the thermometer. Evenings cool slightly once the sun goes down, particularly once the boat is anchored away from the heat the hills hold through the day.
How the season affects diving conditions
Visibility and current strength both shift with the season. Currents tend to be stronger during the peak dry months, which is part of what draws manta rays and larger pelagic fish to feeding and cleaning stations, but also means dive guides plan sites more carefully around slack water. Visibility is generally good throughout the dry season, with many divers finding the clearest water in the middle of the season once plankton levels drop from their wet-season peak. Our Komodo diving guide has more on planning dives around the calendar.
Wind and current
Wind strength has a direct effect on which anchorages and dive sites are comfortable on a given day, which is one reason a fixed day-by-day itinerary rarely survives contact with the actual week. Captains build in flexibility for exactly this, moving a current-exposed stop to whichever day suits it best. None of this is exact enough to plan a single dive around months ahead, which is why experienced captains hold the day-by-day plan loosely until they see conditions on the morning itself.
Sea state and comfort on board
Inside the park's more sheltered channels, seas are generally calm even on a windier day. The more exposed crossings, particularly further from Labuan Bajo, are where wind makes the most difference to comfort. If you are prone to seasickness, our seasickness on a yacht charter guide has practical advice regardless of which month you travel.
Rain outside the dry season
The wet season, roughly November to April, brings more rain, less predictable wind and rougher seas in general, which is why our fleet is not chartering in Komodo during those months. It repositions to Raja Ampat instead, where the calendar runs in the opposite direction. Our Komodo or Raja Ampat comparison explains how the two seasons fit together.
Plan your charter
If your dates are flexible and you want to weigh a quieter shoulder month against the driest peak weeks, send your dates and we can talk through the trade-off, or see which yachts are open for a specific window you already have in mind.
Frequently asked questions
Which month has the calmest seas in Komodo?
Late in the dry season, around September and October, tends to bring calmer seas as the strongest winds of July and August ease off.
Does it rain in Komodo during the dry season?
Rain is uncommon from May to October, though the edges of the season, May, June and October, carry a slightly higher chance of a passing shower than the peak months.
Why is Komodo windier in July and August?
These months sit at the height of the southeast monsoon, which brings stronger, more consistent wind and the currents that draw manta rays and large fish to the park's cleaning stations.
What is the wet season like in Komodo?
Roughly November to April, with more rain and rougher, less predictable seas. Our fleet does not charter in Komodo during this period and repositions to Raja Ampat instead.
Does weather affect the itinerary?
Yes. Captains regularly reorder stops around wind and current, particularly for exposed sites, so treat any day-by-day plan as a shape rather than a fixed schedule.
