The best season to visit the Great Ocean Road in Victoria, Australia, is during the Southern Hemisphere's summer (December to February) or the shoulder seasons of autumn (March to May) and spring (September to November). Summer offers the most reliable "beach weather" with temperatures between 20°C and 30°C, perfect for seeing the Twelve Apostles under clear blue skies. However, this is also the busiest period with the highest traffic. Autumn is considered by many locals to be the "hidden gem" season, as the winds drop, the crowds thin out, and the rainforest sections near the Otways are lush and vibrant. Winter (June to August) can be dramatic and moody with powerful Southern Ocean swells hitting the cliffs—great for photography—but the weather is often cold, wet, and very windy. In 2026, many travelers prefer the spring months, when wildflowers are in bloom and you have a high chance of spotting migrating whales along the Whale Trail near Warrnambool.
