When to use Tides: Earth-Moon 3D Explorer

Last reviewed: 2026-07-17

Reviewed by FreetoolOnline editorial team

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.

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.

Tide mode key figures

Tide mode key figures in one table: Tides Earth Moon 3D Explorer lists spring tides about 1.5x, Moon-only baseline 1x, and neap tides about 0.5x relative range.

Tide mode	Relative range
Spring tide	about 1.5x
Normal (Moon only)	baseline (1x)
Neap tide	about 0.5x

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.
