The First Signs of the Season Underwater 

Sydney divers know when spring has arrived. The mornings are still cool, but the water begins to warm. Baitfish move back into the shallows. Rays cruise across kelp beds at Bare Island. Wobbegongs rest on the sand at Manly. On the right day, visibility stretches further than it has in months. 
 
Divers who wait until summer miss these early changes. Those who dive in spring see the season unfold from the start. 

Why Spring Diving Matters 

Water temperatures climb from 17 to 21 degrees. Marine life is active as species migrate and spawn. Visibility shifts with tides, swell and rainfall. 
 
Spring is also when many divers return after winter. It is the time to reset skills and rebuild confidence before the busy summer months. 

What Happens at Local Sites in Spring? 

Voodoo Point 
The site is famous for its swell and surge. In spring, warmer currents bring pelagic fish close to the rocks. Voodoo Point diving is rewarding but requires care and planning.

 
Manly and Shelly Beach 
Both sites are popular year round. In spring, wobbegongs and rays are seen more often. Calm October mornings suit new divers returning to the water.

 
Kurnell 
Weedy seadragons are active among kelp beds. Between tides the visibility can be excellent, giving divers long encounters with these iconic creatures. 

Why Not Wait Until Summer? 

Spring offers quieter sites before crowds arrive. It gives time for refresher training with instructors. Marine life is more visible in seasonal patterns. Divers also build stamina and confidence for the longer dives of summer. 

How Divers Adjust for Spring Conditions 

Exposure suits 
Water is still cool. Stinger suits or layered wetsuits keep divers comfortable.

 
Gear checks 
Spring is the time to service regulators, check wetsuits and replace straps. A scuba diving gear package is a practical choice for those planning a full season.

 
Safety planning 
Shore divers check forecasts for wind, swell and rain. Conditions change quickly in spring, so knowing the right entry and exit points is important. 

Local Knowledge Makes the Difference 

Spring rewards divers who understand the shifts in Sydney’s conditions. Dive clubs and private guided shore dives give access to that knowledge. Local instructors know which sites clear fastest after rain and which headlands are safe in a southerly. 
 
For those returning after winter, a refresher course helps put buoyancy, navigation and safety checks back in practice. 

Practical Advice for Sydney Divers 

- Plan dives early in the day for calmer water. 
- Bring layered gear for surface intervals. 
- Log water temperatures and visibility to track changes. 
- Start with shorter dives if you have been out of the water for months.
