Tides
Last updated: 2026-09-20
What it does
Shows tide times and heights for your location on any date, with a graph of the tide through the day and a 7-day table. Near the coast it uses real NOAA tide station data. Elsewhere it shows a rough estimate.
What you need
- A location, set with the Location picker. Without one, the screen asks you to set it in Settings.
- A network connection. The tide data is loaded live, so this tool does not work offline.
- The offline estimate is not a device calculation. It also comes from the network request; it is the fallback the app uses when no station is close.
How to use it
- Set your location.
- Read the graph and the NEXT HIGH and NEXT LOW values below it.
- To view another day, drag the date dial, tap the calendar icon beside it to return to today, or pick a date with the calendar field.
- In the 7-Day Tide Table, use the previous and next week arrows to page through weeks.
Reading the results
- Real data: if a NOAA tide station is within 50 miles, the screen shows the station name, its ID, and its distance in miles. These are published tide predictions.
- Estimated: if no station is within range, or the tide service could not be reached, the screen says Estimated and notes that it is a rough Moon-based estimate, not real tide-table data. Do not rely on it for navigation or safety.
- Heights are in feet (imperial) or meters (metric), following your unit setting.
- NEXT HIGH and NEXT LOW skip events that have already passed today and fall through to tomorrow's first event if needed. On other dates they show that day's first event.
- Each row of the week table shows the day's high (H) and low (L) with time and height.
Tips
- An inland location will usually show the estimate, since no station is near.
- If loading fails, the screen says it could not load tide data; try again shortly.
