Where the data comes from
- Air temperature, rainfall, humidity — ERA5 reanalysis (Copernicus / ECMWF) via Open-Meteo, averaged over 2015–2024. Each region uses one point: the resort or city in its caption.
- Sea temperature — Open-Meteo Marine, average sea surface temperature for 2023–2026 (the source has no longer record yet).
- Rainy days — days with at least 1 mm (0.04 in) of rain. Reanalysis picks up light rain more often than weather stations, so treat this as an upper bound.
- Month rating — one rule for every destination, based on three factors: day highs (ideal 75–91°F / 24–33°C), monthly rainfall (ideal under 80 mm / 3.1 in) and, for beach regions, sea temperature (ideal 77°F / 25°C or warmer). All ideal means Excellent; one slightly weaker factor means Good. Mixed means heavy rain (150 mm / 5.9 in or more), highs above 97°F (36°C) or a sea below 70°F (21°C). Off-season means highs of 100°F (38°C) or more, cold below 54°F (12°C), over 350 mm (13.8 in) of rain, or several problems at once. A country's rating follows its best region, so check the regional table.
