The best time to visit Ocean Grove is during the warmer months, specifically from December to February, which is Australia's summer.During this period, the weather is consistently warm and sunny, making it ideal for beach activities and enjoying the coastal lifestyle. The average temperatures range from 20 to 25 degrees Celsius (68-77°F), superb for swimming, surfing, and relaxing on Ocean Grove Main Beach or the calmer Barwon River estuary. Families often find these months superb for a holiday, as school breaks coincide, and there are many outdoor activities for all ages.For those who prefer a slightly quieter experience with pleasant weather, the shoulder seasons of spring (September to November) and autumn (March to May) are also excellent choices. Temperatures are milder, typically ranging from 15 to 20 degrees Celsius (59-68°F), making it comfortable for exploring the local shops, cafes, and walking trails without the peak summer crowds.
