When to use Tides: Earth-Moon 3D Explorer

Use the Tides: Earth-Moon 3D Explorer for a quick browser view of why coasts get two tides a day and how Spring tides differ from Neap tides - skip it when you need a real hydrodynamic tide-prediction model for a specific harbor.

Classroom demos of the two-bulge equilibrium tide model
Comparing Spring tide (about 1.5x) vs Neap tide (about 0.5x) amplitude
One-screen refresher before reading the tidal-locking or moon-phases-3d siblings

This page does not replace a real tide table for a specific port, does not model harbor resonance or storm surge, and does not simulate ocean currents.

Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Tides: Earth-Moon 3D Explorer.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
