Winter Rainfall - Climate Predictions Summary

Vines are now dormant. A wetter than normal season is more likely for most of southeast Australia. Climate influences include a warmer than normal eastern Indian Ocean, a neutral tropical Pacific, and warm local sea surface temperatures.
BOM Details

The chances of receiving above median rainfall during the winter period are 60 to 70% over most of southeast Australia. Such odds mean that for every ten years with similar climate patterns to those currently observed, about six or seven years would be expected to be wetter than average over these areas, while about three or four years would be drier.

Climate influences

The tropical Pacific has remained ENSO-neutral since mid-2012. Climate models surveyed by the Bureau of Meteorology suggest sea surface temperatures in the tropical Pacific Ocean are likely to sit on the cool side of neutral during winter 2013. 

SEA Rainfall Predictions.

Four of five international models surveyed by the Bureau favour the development of a negative Indian Ocean Dipole (IOD) event sometime during winter-spring 2013. A negative IOD during winter-spring increases the chances of above normal rainfall over southeast Australia, which is reflected in the rainfall outlook. 

Warmer than normal ocean surface temperatures currently surround much of the continent. Warmer ocean temperatures can provide more moisture to the atmosphere, which in favourable weather conditions (e.g., interactions with fronts or north-west cloudbands) may result in increased rainfall. 

Climatologists will continue to monitor conditions and outlooks closely for any further developments over the coming months, with information on the likelihood of El NiƱo available fortnightly at the ENSO Wrap-Up. For a summary of Pacific and Indian Ocean outlooks, please see the Climate Model Summary.

McLaren Vale Geology Tours

Over 2 days 75 local grape growers, winemakers and tourism operators explored what lays beneath McLaren Vale.

Beneath the ground McLaren Vale is one of the most complex wine region in the world. It is also the best studied. 

In 2010, leveraging the world class geology map, the McLaren Vale Grape Wine and Tourism Association (MVGWTA), commenced a long term exercise in defining and understanding McLaren Vale grape growing and winemaking.

As part of this process a geology tour has been developed by Philip White - drinkster - Drew Noon and James from DJ's.  

The first two were run last week, 23rd and 24th of May. These tours prove very popular, sold out almost overnight, and James will be looking to get sponsorship so more tours can undertaken ASAP.

The Gateway - In the midst this vegetation lies one of the few exposures of the Tapley's Hill Formation,  700 million year old siltstone - which is the oldest we have in the region.

McLaren Vale Sustainable Winegrowing Australia Online system is launched.

Cary Dreelan from software designers Active Ideas and Irina Santiago from McLaren Vale Grape Wine and Tourism. 
We are very excited to see the new online McLaren Vale Sustainable Winegrowing system - - that was launched last night at the Bocce Club. 

This programme is something we believe in. We are sure your business will see benefits from it, the wider industry, and the region as a whole.

In 2012 the program achieved 145 vineyards representing 38% of the total grapes crushed in the McLaren Vale (or 4.5% in South Australia). This season new registrations are being sort - see the information below.

The new online system makes it possible for our agronomy team to help you with your workbook - if you want information about how please contact us. We are really proud to be a part of this exciting development for the region. 


Register your interest to be part of the program.
Payment of annual fee of $50.00 (link to pay:
If you want to register more than one membership, you can do it at once or separately by clicking on the link above.
A single membership can have multiple sites (if they comply with the rules of the programme).
You can have multiple sites under the same registration when you give the same answers to the same assessment for all the sites involved (all vineyards are organic or you do not irrigate the vineyard, for example).
It might take up to 48 hours to process your payment. 
Log into thewebsite.
MVGWTA will inform you by email that you are an authorised user as soon as they confirm your payment.
To become a member, you need to complete the steps above by July 8, 2013The deadline is necessary because they can only start the calculations to produce your results once they are sure about our total members.  Many of the calculations are based on comparisons of your performance with regional averages.
