Sydney Dive Site Hints

	"Sea dragons have a range of less than 110 metres"

Diving Weather and Sea Conditions

Current Conditions at my home at Kareela, Sydney..

The following are some links to diving weather resources as well as sea conditions.

WEATHER FORECASTS AND CURRENT CONDITIONS

Current Sydney Weather Observations - Especially good for seeing if winds are too strong - look at Little Bay and Kurnell for Botany Bay, Kurnell and Wattamolla for Port Hacking and North Head for Sydney Harbour

Current NSW Weather Observations - For Sydney, good to check Illawarra and South Coast locations to see if a change is coming

Sydney MetEye Marine Forecast from BOM - we used this a bit when sailing and seems good

Terrey Hills 64 km Radar - Sydney Weather Radar

Sydney Tide Times

Willy Weather for Cronulla - Computer modelling of winds and sea conditions - very accurate

Buoy Weather for Sydney - US computer modelling - very accurate but only two days in advance.

Current Wave Heights - Sydney

Sydney Ports Wind and Sea Conditions - good for Bare Island and Inscription Point in Botany Bay

NSW Nearshore Wave Tool - Forecast of waves and swell at thousands of locations. This link goes to Bare Island. My experience is that it often understates the height considerably.

SPECIFIC DIVE RELATED FORECASTS

The following sites show predicted conditions at certain shore dive sites in the Sydney area. Both use data from other sources and combine it together to show if the dive site is safe to dive and expected roughness and surge. I was involved in assisting both, one by providing comments on the original implementation and the other with data from my website about the site. Both are quite good and mostly accurate in my experience.

HOW TO INTERPRET WEATHER FORECASTS FOR DIVING

Wave period and surge - an explanation of how it impacts on diving.

Sydney Water Visibility, Swell and Temperature Averages by Month - from my dive logs over about 28 years

How Weather Affects Conditions for Diving in Sydney - from my 35 plus years of experience diving in Sydney
