We recently shifted our ENSO Outlook to LA NIÑA.
This follows a steady cooling of the central to eastern tropical Pacific Ocean since late winter. Waters in this area have now reached La Niña thresholds (0.8 °C below average), and atmospheric indicators, including the Southern Oscillation Index (SOI), trade winds and cloud patterns, are also at La Niña levels.
However, this La Niña is likely to be weaker than recent events, far shorter-lived, and not expected to continue far into autumn. So what does that mean for Australia's climate over the coming months, and what actually is La Niña?

After thorough testing with registered users, we added 20 new catchments to the Bureau’s 7-day streamflow forecast service in early December.
This service provides streamflow forecasts with a lead time of up to seven days, to help river managers and users with decision-making.

With this expansion, the public service will deliver forecasts for 88 catchments and 168 forecast locations across the country.

We have recently released the northern Australia region accounts—Burdekin, Daly and Ord—of the National Water Account 2017

Overall, in northern Australia for the 2016–17 financial year:

Total water use was about 8% less than the previous year due to wetter conditions.

You are invited to contribute to the review of Australia's guidelines for the use of Acoustic Doppler technology in streamflow measurement.

It's been more than four years since the National Industry Guidelines for hydrometric monitoring were published by the Bureau. To keep pace with changes in technology and practice, they're now due for review.

Read more about seeking comment on hydrometric guidelines.

Rainfall conditions 1 July 2015 to 30 June 2016
Annual rainfall conditions 2015–16

The Bureau’s Water in Australia 2015–16 report shows that reserves in storages declined by seven per cent during the 2015–16 year. Despite annual rainfall being near average, it fell at the wrong time of year in many areas so reserves were drawn down.
