Fishing Bay Area / Monterey

The Bay Area and Monterey grounds are a classic West Coast upwelling fishery, and the water here can change character over just a few miles. Northwest wind drives cold, nutrient rich water up from depth along the coast, and that cold green water pushes out to meet the warmer, cleaner blue water offshore. The seam where the two meet is the edge you are hunting. On a good push that temperature break can set up anywhere from a few miles outside the Golden Gate to well out past the shelf, and it moves with the wind and the swell.

Structure does a lot of the work for you here. The continental shelf drops off and is cut by real canyons, and the Monterey Canyon is one of the deepest and most dramatic on the entire coast, swinging close to shore and funneling cold water and bait. The sea mounts and banks offshore, places like Pioneer and the Guide Seamount, stack bait when the current hits them. A temperature break sitting on or near that kind of structure is far more productive than the same break over flat, deep water, which is exactly what the chart is built to show you.

Seasonally, the summer and fall upwelling season is when most crews run offshore. Albacore tuna show in the warmer blue water offshore when it pushes in, and in warmer years bluefin tuna have become a serious target closer to home. Salmon, rockfish, halibut and white seabass fill out the nearshore and shelf fishing. Dungeness crab opens into the colder months. None of this is a guarantee, conditions and seasons shift every year, but the pattern of cold green meeting warm blue over structure is the constant.

The move is simple. Before you leave the dock, read where the break is sitting, line it up against the canyon and the shelf edge and the color change, and plan your run so you are fishing the edge instead of looking for it on expensive fuel.

I've tried every temp map out there and they all feel like they were built ten years ago. I'm not exactly a tech guy, but this one actually makes sense the second you open it. First time using it, I marked a break in about 30 seconds the night before and boated bluefin right on it the next morning.

Used to burn half a tank driving around looking for color change or a solid temp break. Now I check ReelTemps before I leave the dock and I know exactly where I'm going. Less time driving around guessing, more time with lines in the water.

Albacore season used to mean a couple hours of homework the night before and just hoping it held up. Now I do most of my research that morning and pull it up on my phone if things change once we're out there. Makes calling an audible a lot easier.

Bay Area / Monterey FAQ

Where does the temperature break usually set up off the Bay Area?
It depends on the wind. During strong northwest upwelling the cold green water hugs the coast and the break pushes offshore, sometimes past the shelf. When the wind lays down, warmer water slides in closer. The chart shows you where it is sitting that day instead of guessing.
How does Monterey Canyon affect the fishing?
The canyon swings close to shore and funnels cold, nutrient rich water and bait up from deep water. A temperature break or color edge sitting over the canyon rim concentrates life, which is why the depth contours and the SST layer together tell you more than either one alone.
What do people target offshore here?
Albacore in the warm blue water offshore, and in warmer years bluefin tuna closer to home, through the summer and fall. Salmon, rockfish and halibut work the nearshore and shelf. Seasons and regulations change every year, so always check current rules.
Is the Bay Area chart buoy calibrated?
Yes. There are active NOAA buoys in and around the region, so the satellite SST can be checked against real in water readings. Remember that satellite and in water temperatures can still differ.
