Salish Tides
Offline Tidal Currents
Free · Designed for iPad. Not verified for macOS.
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
