September and October are typically the slowest months of the year for fishing on Costa Rica’s famed Pacific Coast. The reason why is two-fold: these two months are typically the wettest months of the year and the heart of our rainy season, and because of that many tourists get scared away so there aren’t that many anglers out fishing. The truth is the sun shines just about every day in Costa Rica, and if you do get rain it’s almost always in the afternoon. Unless there is a storm system offshore or a tropical depression hovering over the country, the weather is quite nice and very predictable. To be more specific, the fishing in Guanacaste is actually at it’s peak in September & October and as that happens to be the hottest and driest region of the country a fishing vacation there during these months is often just as good as a fishing vacation to Los Suenos or Quepos in the heart of peak season.
That said, like all fishing destinations some years are better than others and the reasons why are complex and interwoven. 2018 in Costa Rica was a banner year for dorado (mahi mahi), the best its been in the past decade, and the yellow-fin tuna and marlin bite were fantastic. The sailfish numbers were down for the second year in a row, but with all the meat fish around anglers were still going home happy. We knew it would be a great green season for fishing because of the presence of all these pelagics, but the fishing got an added boost with drier-than-normal weather this year. To be clear 2018 was NOT an El Niño year, it’s simply that the waters in the Caribbean were colder than normal which made the Pacfiic Coast drier than the yearly averages. The combination of tons of pelagic fish and dry weather led to some epic fishing days, so for anyone who was smart enough to ignore over-blown horror stories of 24-7 monsoons, hurricanes, and flooding they experienced some fantastic sport fishing in Costa Rica. The inshore fishing for roosterfish remained strong these months too as many anglers hauled in 40-60 lb beasts. Below you can see our Costa Rica Fishing Report for September & October 2018:
