Leidora is an interactive climate map for planning trips. Pick a month and see temperature, rain, sunshine, snow and sea temperature across every land area on Earth. Tap any place for its whole year in one chart.
Open the mapSwitch between average temperature, daily highs and nightly lows, rain, sunshine and snow, and step through the twelve months to watch the seasons move.
Tap a spot to see its typical day and night temperature, rain and sunshine, with a twelve-month chart that shows the best time to visit.
A 0–100 score for the coast that weighs the water first, then the afternoon heat, rain and clear sky. A sunny coast with a cold sea scores low.
Shortlist places and see them side by side, month by month.
Switch to the 11 km grid to see mountains, coasts and islands sharply. Zoom in and each cell's outline shows the area its value covers.
The address carries the month, the layer, the map position and the place you opened, so a link shows the other person the same view.
The parts are multiplied, not added, so one weak part pulls the whole score down: a perfect sky cannot rescue an 18 °C sea. Scores fall into classes from Poor to Excellent (90 and above), and only cells on the coast get one.
From ECMWF's ERA5-Land climate reanalysis on a 0.1° grid, averaged over 2011–2025; daily max/min 2016–2024 (5 selected years); sea temperature and cloud cover come from ERA5 at 0.25°. It is what a typical month looks like, not a forecast or any single year.
No. Leidora shows long-term averages, for planning trips weeks or months ahead. For the next few days, use a forecast.
Each value is an average over a grid cell about 11 km (HD) or 22 km across, so it describes the area's climate, not one street or one beach.
Lubomír Tomány, as a hobby project. The name comes from Old Norse leið, the course a journey takes, as in lodestar, the star that guides it.
