About

Coastya is a map of the world's beaches, built on public climate and ocean data.

Every climate figure is a long-term average for 1991–2020 — what the sea and the sky usually do in a given month, not what they are doing today — and next to it, what actually happened in that month from 2020 to 2025. Where we do not have a reliable number, we say so rather than guess.
