How we ranked these

Each destination is scored 0–100. The main signal is the share of trip days whose daily high falls inside your 22°C and above preference, followed by how many days stay dry (under 1 mm of rain). Forecast confidence (real forecasts beat climate normals) and proximity to Oslo contribute the remaining weight.
