Two seasons, not four
El Salvador has a dry season from about November to April and a rainy season from about May to October. The U.S. State Department notes that flooding and landslides are common in the rainy season (May–October) and that hurricane season runs June through November[1]. Afternoon storms are the usual pattern; one third-party guide says rainy-season mornings are often sunny, with choppier seas and lower prices[2].
Reported peak windows
We found no official catch statistics by month for recreational fishing. The table below shows what published sources say, side by side, so you can see where they agree and where they don't. Treat the shaded months as "reported good", not as a guarantee.

What the sources disagree on
- Sailfish start and end. Fishing World Guide gives November–April on one page and November–May on another[2][3]; The AdvenTourist says October–March[4]. Late October and May are shoulder months.
- Blue marlin. Most sources group marlin with the dry-season sailfish run, but we found no strong primary data on a marlin peak. The international tournament is held each November and features both[5][6].
Dates worth knowing
- El Salvador International Billfish Tournament: the 32nd edition runs November 12–16, 2026, at Hotel Bahía del Sol, Costa del Sol, with fishing days November 13–15[5][7]. It is a total-release event: a boat that brings a marlin or sailfish ashore is disqualified, and non-offset circle hooks are mandatory with natural baits[7]. The organizers say the tournament dates back to 1995. Expect boats and rooms near Costa del Sol to be busy that week. Register on the official site ↗
- Christmas and Semana Santa (Easter week) are busy domestic travel periods. Book boats and rooms early.
Picking your month
If billfish are the goal and you want the calmest, driest weather, aim for December through March, the overlap of every source above. If you care more about price and don't mind afternoon rain, the rainy season still offers dorado, tuna and inshore fishing, and it is the only window cited for tarpon. Wherever you land, ask your captain what has been biting in the past two weeks; local reports change faster than any guide. See how to book.
