Dec – Feb
The best window
The dry season at its most settled: calm sea, the clearest water of the year and every route running. It is also the busiest, so the lagoons fill by mid-morning and private boats are worth booking ahead.
Timing
Palawan has a dry season and a wet one, and the difference is not whether boats go out. It is which of the four routes can run, and how many other boats are in the lagoon with you.

Quick answer
December to April is the dry season and the reliable window for island hopping in El Nido. The wet season runs roughly June to November, with September and October the roughest. In the wet months the sheltered stops usually still run, but Tour C is cancelled first and the Coron expedition is the most weather-dependent thing here.
When to come
The question is not rain. It is sea state, and which of the four routes it stops.
Dec – Feb
The dry season at its most settled: calm sea, the clearest water of the year and every route running. It is also the busiest, so the lagoons fill by mid-morning and private boats are worth booking ahead.
Mar – May
Still dry and getting very hot, with the warmest water of the year. Crowds thin after the February peak, which makes April and May a good compromise.
Jun – Aug
Rain comes in bursts rather than all day. Tour A usually runs; Tour C is cancelled more often because its stops are exposed. Prices drop and the lagoons are quiet.
Sep – Nov
The most cancellations of the year, particularly for Tour C and the Coron expeditions. Boats go on good days, prices are lowest, and a flexible plan is essential.
What the wet season actually stops
Tour A runs almost always; Tour C and the Coron crossing are what the weather stops.
Tour A is the sheltered one. Its stops sit inside protected arms of Bacuit Bay, so it runs on days when other routes do not.
Tour C is the first cancelled. Matinloc and Tapiutan face open water, and Secret Beach needs calm because you swim in through a gap in the rock.
The Coron expedition is the most weather-dependent thing on this page. It crosses open sea for three days, and in September and October it is called off often.
And there is an upside to the wet months. The lagoons are empty. If the choice is between a crowded Big Lagoon in February and an empty one in July with a chance of rain, a lot of people would take July.
Common questions
December to April, the dry season. It has the calmest sea, the clearest water and every route running.
Roughly June to November, with September and October the roughest and wettest.
Usually yes for Tour A, which is the sheltered route. Tour C is cancelled more often, and the Coron expeditions most often of all.
Yes, and the lagoons are far quieter. The trade is a flexible plan.
As early as possible. In the dry season the Big Lagoon has a queue by mid-morning.
December to February. Book private boats ahead in those months.
