The best time to go to Shelly Beach for pleasant weather and outdoor activities is during the shoulder seasons of April to May and September to November.These months offer warm temperatures, generally ranging from the low 70s to low 80s Fahrenheit (22-28°C), with less rainfall compared to the summer and milder conditions than the winter. This makes it ideal for enjoying the beaches, water sports like snorkeling and diving, and exploring the surrounding nature reserves without the peak crowds of summer.For travelers looking to minimize crowds, the period from September to November is particularly appealing. The ocean temperatures are comfortable for swimming, and you'll find a more relaxed atmosphere on the beaches and in local establishments. It's also a good time for whale watching, as humpback and southern right whales are often seen along the coast during their migration.If you're planning a trip focused on beach activities and don't mind warmer, more humid conditions with occasional thunderstorms, the summer months of December to February are also an option. However, this is peak season, meaning higher prices and more people.
