How this app works
This app shows tide extremes (highs and lows) for your location using data
from the
Stormglass.io API.
- Tide times and heights are relative to
Mean Sea Level
(MSL).
- Most public tide apps show height relative to
Chart Datum
(CD), which is often lower.
- You can estimate CD height by adding an offset (e.g. +4.17 m in Brest,
France).
Storage
Your API key and tide data are saved in your browser's local storage.
Change coordinates anytime to get tides for a new location.
Updating
Tide data updates daily. Use the "Update Tides" button after a day has
passed.
