Sail Tactics

Welcome to the home of the highest-resolution wind-sport forecasts in the world. Our forecasts actually see all of the mountains, sea breezes, gaps, and islands that make sailing fun and challenging. We custom tune our forecasts to each region we offer.

Our Forecast Schedule


8am (7am winter) - Sunset
Our highest-resolution and most accurate forecasts. We make these forecasts fresh every morning to provide unmatched accuracy. Resolutions go as high as 200 m to help you win.


2-Day Outlook
High-resolution (1000 m) forecasts for the next two days, to help you enjoy your next sail. Useful to determine which sails to bring and how many crew you need. Race committees, cruisers, and kite/surfboarders love em too.


Post-Race Analysys
Use these forecasts for post-race/sail analysis, as well as to determine the accuracy of the forecasts compared to your on-the-water observations.

Why Use Sail Tactics Forecasts?

Freshest Forecasts

We run “just-in-time” forecasts every morning to get you the most accurate forecast possible. Using the morning Oakland weather balloon, we resolve marine layer flows better than anyone else.

Our Subscribers Win

Our subscribers have won nearly every major race on San Francisco Bay, and they continue to win. Having access to our forecast has become almost necessary to be in the know on race day.


We use a state-of-the-art weather forecasting model that knows the surface type (drag from trees, buildings, bridges, etc.), water surface temperature, and the place you sail's unique terrain.

Highest-Resolution Forecasts

We have the most resolved forecasts in the world. Other models don’t see the Golden Gate in full-detail or Angel Island at all. We let you know how close you can get to the lee of Angel Island and what to expect in the “Slot”.

We’re Out There With You

We know our forecasts are the best because we personally have used them for years on the San Francisco Bay. We got feedback from fellow racers who were often in the boat next to us or the race committee who was relying on our forecast to pull off a top notch event.

New Features

We are never satisfied with the status quo. Forecasts are improving all of the time thanks to advances in science and computing. We believe your sailing forecast should be getting better too.

First place at Rolex Big Boat Series!

“Sail Tactics helped me guide our boat to first place at Big Boat Series in the CA Farr 40 class. Thanks again for your service.”

Actually predict the sea breeze

“I think Sail Tactics wind forecasts actually predict the sea breeze in the San Francisco Bay, which SailFlow, NOAA, and others seem unable to do.”
