Wind & Tides vs BayCurrents

A wind map up to 14 days ahead, NOAA nautical charts with your GPS position, the marine forecast from your local NWS office, live buoy reports, tides and currents: everything you check before leaving the dock, in one app for your home waters. One-time purchase. No subscription, no account, no ads. The wind map and NOAA charts cover US waters wherever NOAA publishes a chart. The marine forecast, live buoy reports, tides and currents are per region: 30 regions so far, listed below. If your home waters aren't there yet, request them at windandtides.com. Built for boating, sailing, fishing, kayaking, paddleboarding, windsurfing, wing foiling, kiteboarding, and open water swimming. Sailors have used Wind and Tides since 2011, and the marine and weather forecasts, tides, currents and buoy reports each link back to their NOAA source page.

BayCurrents is a mobile app for displaying maps of high resolution surface currents within the San Francisco Bay. The app is intended to support a wide range of maritime activities, from recreational fishing and sailing to the operation of professional transport vessels. The source for the surface current data is a numerical model operated by the National Oceanic & Atmospheric Administration (NOAA). The model benefits from oceanographic high-frequency radar (HFR) measurements from the Central & Northern California Ocean Observing System (CeNCOOS) HFR Network, along with other observations such as tides and wind. The resulting dataset contains current vector fields for hourly timestamps ranging from the recent past, to the present and up to 48 hours into the future. The complete vector dataset is downloaded by the app to allow autonomous offline operation. This app contains experimental data and is NOT for navigational purposes.
