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. Forecast confidence (real forecasts beat climate normals) and proximity to London contribute the remaining weight.

Weather data from Open-Meteo, generated 2026-05-31. Drive distances are great-circle approximations — set ORS_API_KEY in your environment for real road distances.
