Typical weather, not a forecast: averages for 2021–2025 (air, rain, wind) and 2023–2025 (sea), data from Open-Meteo (ERA5 / Copernicus, Météo-France). Covers an area of roughly 10 to 25 km around the destination.
Scuba Diver Life and PADI give April–October as the diving/boat season; the Lundy Field Society says visibility is good enough from the end of April to the end of September (May–Sep shown as best, Apr and Oct as good). Nov–Mar is shown as closed because Scuba Diver Life says diving is 'only possible from April to October'; however, SSI says Lundy 'can be accessed year round for diving if the weather allows' (summer best). Seal breeding-season restrictions apply in autumn.
Usually closed or not dived: Nov–Mar.
