Field notes
Oceanic temperate (Welsh coast) — meaningfully wetter than the English peers because of the Atlantic-facing Welsh-coast position. Winter (December–February, 5–6°C average) is mild and damp. Summer (June–August, 16–18°C average) is mild and pleasant when not raining. The Brecon Beacons inland produce a slight rain-shadow effect for Cardiff itself. Spring and summer (April–August) are the cleanest working windows.
