Spring is a transition period around Los Cabos. March and April remain within the current October–April striped-marlin planning emphasis; fish may still be encountered in May as water conditions change. The useful area can move between the Pacific side, the cape and the Gulf of California side.
Why spring can work
March and April are the stronger calendar starting point, while May is a transition rather than a promised extension of the season. Changing water edges, mobile bait, patchy water and wind can all alter where fish are found. A “peak” label or temperature threshold cannot establish where fish will be during a particular week.
Before travel, ask for evidence from the preceding several days:
- Where has bait been seen?
- Are fish being found feeding, tailing, or only on electronics?
- How long is the likely run from the departure marina?
- What target makes sense if the marlin plan fails?
Common techniques
Crews may troll lures or rigged baits to search, switch to live or dead bait when fish are located, or cast to visible fish. Boat speed, bait species, hook and leader should match the captain’s method and the release plan.
A moving set of grounds
Gordo, Iman, San Jaime and other named banks describe broad fishing areas. Current, bait, wind and recent fleet information help the captain choose the search area and route using current SEMAR charts.
Release first
Mexico’s general sport rule permits one retained fish total from the marlin, sailfish, swordfish, shark and giant-sea-bass group per angler per day, and that fish counts as five toward the ten-fish marine allowance. Release is still the responsible default for billfish. Agree on in-water handling and photographs before the hookup.
