Summer (December to February): Best for Beaches
Summer is the busiest and most popular time to visit the Mornington Peninsula. Average daytime temperatures sit between 20°C and 30°C, and the days are long, with sunlight lasting until well past 8:30 pm in December and January.
This is the season for:
- Swimming and sunbathing at Mornington, Dromana, and Mount Martha beaches
- Surfing the ocean-side breaks at Gunnamatta and Rye
- Long alfresco lunches at vineyard restaurants
- Dolphin and seal swim tours from Sorrento and Portsea
January is the busiest month of the year, so book accommodation and restaurants well ahead. If you’re flying in for a beach holiday, it also helps to know your way around before you land — this guide on how many airports are in Melbourne is a handy read for first-time visitors working out which airport to fly into.
Good to know: Summer brings the heaviest traffic on the Nepean Highway, especially on weekends. If you’re travelling down from the city or the airport, arranging a taxi ahead of time can save you the stress of holiday traffic and parking at the beach towns.
Autumn (March to May): Best for Wine and Mild Weather
Many locals consider autumn the true best time to visit the Mornington Peninsula. The summer crowds thin out, the weather cools to a comfortable range, and the region’s wineries come alive with harvest season.
Why autumn works so well:
- Cellar doors pour fresh vintages straight from harvest
- Cooler air makes coastal walks and scenic drives more enjoyable
- Vineyards turn shades of red and gold, perfect for photos
- Weekday visits mean shorter waits at popular wineries
If your trip includes wine touring, group travel is worth thinking through early. Larger families or friend groups heading to multiple cellar doors often find it easier to compare options like a maxi taxi vs mini bus before booking, since the right vehicle size can make a winery day far more comfortable.
Spring (September to November): Best for Wildflowers and Quiet Sightseeing
Spring is the quietest tourism season on the Mornington Peninsula, which makes it a smart pick for travellers who want easy restaurant bookings and uncrowded walking trails. Wildflowers bloom along the coastal cliffs, and temperatures climb gradually through the season.
Spring highlights include:
- Blooming gardens and flower festivals
- Shearwater birds returning to nest along the coast (September to November)
- Local food, art, and music festivals, including the popular Mornington Main Street Festival in October
- Comfortable weather for hiking and cycling without summer heat
Spring weather can change quickly, so pack a light jacket even on a sunny-looking day. If you’re connecting from another airport during a spring getaway, this guide to travelling from Mornington Peninsula to Avalon Airport by taxi covers timing and travel options worth knowing in advance.
Winter (June to August): Best for Hot Springs and Budget Travel
Winter is the off-season, and that’s exactly why many travellers choose it. Crowds disappear, prices on accommodation often drop, and the cooler weather makes warm, cosy activities feel even better.
Top winter experiences:
- Soaking in the steaming mineral pools at Peninsula Hot Springs
- Fireside seating and hearty winter menus at wineries like Polperro and Main Ridge Estate
- The Winter Wine Weekend, usually held in June
- Quiet coastal walks through Mornington Peninsula National Park
Days are shorter in winter, with under 10 hours of daylight around the June solstice, so plan outdoor activities for late morning through early afternoon when the light is best.
