Coral needs warm water to live and grow, and the sea around the Great Barrier Reef maintains a steady water temperature of between 71F or 22C to 28F or 82C throughout the year. Diving, surfing and sailing are all popular pastimes in this glorious region, and you’re almost guaranteed great conditions.
Whether you’re a beginner or an experienced diver there are sites that are perfect for you, and numerous dive schools and boat charters cater to all levels. The reef is a protected natural environment so do check which areas allow certain activities.
Best time to visit the Great Barrier Reef
Any time of year is perfect for a trip to the Great Barrier Reef. However, during the ‘green season’ which lasts from December to March tropical downpours through the night are likely. On the plus side, mornings tend to be glorious and sunny with light trade winds, the perfect climate for sailing holidays or diving and surfing trips.
Throughout the rest of the year, the clear, unspoiled waters are ideal for swimming and other water sports in designated areas, and the seas around the Great Barrier Reef are considered among the world’s cleanest.
