Salish Tides

Salish Tides is an offline-first map of tidal currents and tide heights for the Salish Sea. When you're online it shows real-time surface-current forecasts from the SalishSeaCast model. When you're offline it falls back to harmonic predictions computed on your device — so it keeps working with no signal.

It's a planning aid for paddlers, sailors, and anyone who works around the tide.

It's a passion project - something I found genuinely useful - made possible by people smarter than me - s/o all the researchers and scientists who worked on the models.

I did draw the logo all by myself.

Made for the water • Light, dark, and satellite themes • Shows your GPS position on the map

The data

• SalishSeaCast ocean model (UBC)
• Tide heights come from NOAA Tides & Currents and the Canadian Hydrographic Service.

Salish Tides is a planning aid, not an official source for navigation. Always consult official charts, tide tables, and current atlases, and keep a proper watch.
