A live tide chart for your website

Live tide times for 27,218 coastal locations, on your page. Pick a place, choose a size and a theme, and copy two lines of HTML. Free — for everyone, forever.

Live right now at Istanbul.

Server-rendered HTML in an <iframe> — no script tag to install, nothing that can break your page.
Under 20 KB, one request, no webfonts. It loads lazily and costs your visitors almost nothing.
No cookies, no tracking, no ads — in the widget or anywhere else on this site.
Light, dark, or automatic: it follows whatever your reader has chosen.

The only thing we ask is the small attribution link that comes with the code. It stays for everybody — there is no paid tier that removes it.

How it works

Choose a location. Every location we publish has its own widget.
Set it up. Size, theme, units and which blocks to show — the preview is the real widget, not a mockup.
Paste two lines. The frame draws the tide; the line under it is a plain link back to the location's page.

The widget re-renders on every page load, so it is never out of date. Heights are predictions for planning, not for navigation — the same caveat that applies everywhere on this site.
