SYDNEY - HOBART QUESTIONNAIRE




We hope that the service from the Bureau of Meteorology will provide you with timely and accurate information, to enhance the safety of your passage to Hobart and also the chance to gain a competitive edge. In our endeavour to continue improving our services for this race, please take some time to answer the following questions and return this form in the reply paid envelope supplied. Wishing you a safe, fun and exciting race.

Brett Gage, Marine Weather Manager NSW.


Did you use the internet, weather fax, mobile phone or radio to access weather information during the race and did you experience any difficulties with the mode of access you used?





Which products did you find most useful?






Was the Sydney - Hobart forecast reasonably accurate and if not, when and why?









Did the meso-scale charts provide good guidance against observed conditions and if not, which product was lacking accuracy and at what time and day?








Is there any weather information that you know of, that was not provided in the weather pack, that you would like to be included for next years race?

Latest NSW Coastal Wave Heights

The information avalable from here is routinely updated at 00:40, 03:40, 09:40 and 15:40 Hrs Australian Eastern Standard Time. If large waves (over 3.5m Hsig) are present at any of the sites then all sites will be updated at about 40 minutes past each hour.

The map beside the plots represents the latest available sea surface temperature and is derived from a CSIRO marine Research remote Sensing Project satellite image.

TIDE PREDICTIONS FOR HOBART
DECEMBER - 1998
tide predictions

National Tidal Facility - Paul Davill


Sydney Predicted Tide

Predicted tidal levels for other New South Wales ocean locations will vary from those at Sydney although, in general, the variation will not be more than 0.2 metres. The maximum time difference for other NSW coastal ports is up to 10 minutes. The actual tide may differ from the predicted tide due to meteorological and oceanographic conditions. Zero on the tide plot is Indian Springs Low Water, which is approximately the level of the Lowest Astronomical Tide.

Data similar to this and much more generally useful information is published in the NSW Tide Charts. predicted tide

Note: All times are Australian Eastern Standard Time.

Important: These predictions have been generated from data recorded by MHL and are NOT the official tide predictions for Sydney and should not be used for navigational purposes.

For inquiries about this data contact Col Nalty, CNalty@mhl.nsw.au.
