Fishing

Pacific bluefin are the cold-tolerant tuna — caught off California from the mid-50s into the low 70s °F. The number that matters isn’t the absolute temperature but the edge: the break where warm bight water bumps against cooler upwelled water.

Hover the chart to read the water anywhere — temperature, typical depth, range from the harbor, and whether you’re inside an MPA. Scroll or pinch to zoom, drag to pan (one finger pans on a phone once you’re zoomed in), double-click to zoom further, and the dashed rings are 20, 40, and 60 nm from the harbor mouth; runs and bearings (magnetic, var 12.5°E) are computed great-circle from the harbor. Scrub back through the week of NOAA analyses to watch the break move, or forward past the latest analysis: forward days switch to an ocean-model forecast, drawn with dashed isotherms — coarser than the 5 km analysis, so trust the break’s trend more than its exact position. The wind layer follows the day you pick. The dash-dot line is the Channel Islands National Marine Sanctuary boundary and the violet patches are state and federal MPAs (zoom in for their names) — boundaries, depths, and spot marks are all indicative, so verify against official charts and the current CDFW regulations before you go. A chart for planning, not navigation.
