About Iceland

Iceland is a volcanic island in the North Atlantic, shaped by glaciers, lava fields, hot springs and a treeless interior highland. The Golden Circle, the south coast's waterfalls and glacier lagoons, and the Westfjords and Eastfjords spread its highlights around the island. Summer from June to August brings midnight sun and open highland roads, winter is dark and cold but good for northern lights, and spring and autumn sit quietly between them.

How are the Iceland travel scores calculated?
Every city is rated 0-10 per month using ERA5 climate normals - temperature, precipitation, humidity, daylight, and days with 6+ hours of sunshine.

Climate data: Open-Meteo ERA5 historical archive, the five most recent complete years (2021–2025). Scores are monthly averages for that window, not forecasts, and short-window precipitation can differ from longer-term normals. “Sunny days” count days with at least 6 hours of measured sunshine — they are not dry days.
