About Ireland

Ireland is a green Atlantic island of rolling fields, bogland and dramatic sea cliffs, with a strong literary and musical tradition. Dublin and Galway anchor the east and west coasts, the Cliffs of Moher and the Ring of Kerry draw visitors to the southwest, and the north offers wilder coastline. Summer is the warmest and busiest season, spring and autumn are quieter and still mild, and winter is wet, windy and calm for indoor city trips.

How are the Ireland 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.
