Answers to common questions. For anything else, email us.
Where does the data come from?
Tide predictions come from NOAA CO-OPS, for the nearest of about 3,500 stations. Wind and temperature come from Apple Weather.
Why is my station far away?
Ebbmark shows the nearest NOAA station to you, and on some coasts that station can be many miles away. Open Stations in the app to choose a different one.
Does it work outside the US?
Ebbmark is made for US coasts and uses NOAA stations. There are no NOAA predictions outside the US, so the app has nothing to show there.
Is it for navigation?
No. Predictions are for planning your day. They do not include the effect of weather, and they are not for navigation.
