The best time to go to Manly is during the summer months, from December to February, when the weather is warm and sunny, great for enjoying the beaches and outdoor activities.
During this period, you can expect average temperatures around 20-25°C (68-77°F), with long daylight hours. It's the ideal time for swimming, sunbathing, and exploring the coastal walks. However, it is also the busiest time, so booking accommodation and popular activities in advance is highly recommended.
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, usually ranging from 15-20°C (59-68°F), and there are fewer crowds. You can still enjoy many outdoor activities, and you might find better value on flights and accommodation.
Winter, from June to August, brings cooler temperatures and more rainfall, but it can still be a good time for a relaxing getaway if you don't mind the cooler weather.
