Get High And Low Tide Predictions From The NOAA API

January 2025

Notes

There is generally 10 years worth of data available, but don't try to get it all at the same time for a single station. It often causes a gateway timeout as it looks like the data doesn't get generated fast enough. Going year by year instead seems to work fine.
