    Tonight:

    Rain will gradually clear to the east with scattered showers to follow through this evening. Some dry, clear spells developing overnight, but remaining breezy for all. Minimum temperature 10 °C.

    Sunday:

    A bright day with blustery showers. Heavy, sometimes thundery downpours are expected throughout the day, interspersed with drier, sunnier spells. Feeling especially windy along the coast. Maximum temperature 19 °C.
