About these figures
Medium confidence: tropical areas are scored mainly on rain and sticky heat, which a climate model captures less exactly than temperature, so we never give them our highest confidence rating.
Day temperatures from ERA5-Land, adjusted for altitude with a tropical correction; monthly rain from CHIRPS satellite rainfall; sunshine from ERA5 direct sunlight; sea temperature from ERA5 about 35 km offshore. Averages for 2004–2023.
Scores are estimates from modelled climate data, not forecasts. How we score.
