Next 180 Days - Weather predictions & trends for the season

What is the Next 180 Days feature used for?

This feature provides insight into how the season is expected to progress.

This insightful information will help you prepare for the season across your various sites and help to answer questions like, “Will the upcoming El Niño and Positive IOD impact the weather on my vineyards in Southern Tasmania in a similar way to the rest of my portfolio across Southern Australia? Or will the impact be limited?”

Where can I find Next 180 Days in the mobile app?

The new feature is located in Growing Conditions under the tab “Next 180”. When you open this tab you will see today’s conditions as well as the latest observations, scroll down to see the Next 28 Day calendar and the Next 6 Monthly charts. 

How are the Next 180 Days determined?

The seasonal weather in Australia and New Zealand is driven by five major climate drivers:

• The Sun
• El Niño Oscillation Index (ENSO)
• Indian Ocean Dipole (IOD)
• Madden-Julian Oscillation (MJO)
• Southern Annular Mode (SAM)

Next 180 Days helps to predict how these climate drivers will affect the weather that your sites experience over the next six months.

Current forecasts suggest that:

• El Niño will develop later in 2023
• The Indian Ocean Dipole (IOD) will soon shift to positive
• The Southern Annular Mode (SAM) index will return to neutral towards the end of May

The Yield’s Seasonal Forecast Model combines these factors and provides you with temperature and rainfall predictions for the Next 180 Days.

How is the forecast is calculated?

The Next 14 Days (dates shown with “・”) of this forecast are produced by The Yield's patented forecast model and are updated up to four times a day. 

The forecast for the following six months is generated from The Yield’s Seasonal Forecast Model. This is based on an 18-mile (29 km) grid and is updated once per month. 

As with any long term forecast, confidence in the outcome decreases as the lead time lengthens. These forecasts should be used as a guide only.

The Long Term Average is based on the gridded ERA-5 dataset and is the average for the 30 year period 1991-2020.
