What is the weather in Frankston typically like?

Spring and autumn offer the most settled window for outdoor plans, with crisp mornings and mild afternoons.
What should I pack for a trip to Frankston?
Regardless of season, a windproof jacket is your friend—the bay breeze catches many visitors off guard. In summer, bring a light jumper for evenings; in winter, a proper raincoat and warm layers. Comfortable walking shoes are a must for the Frankston foreshore trails. Sunglasses and sunscreen are essential year-round.
