National temperature outlook
Issued 22 January 2014
The February to April maximum temperature outlook shows chances of greater than 60% for warmer than normal days over Tasmania, east Gippsland in Victoria, and southeast NSW (see map). So for every ten February to April outlooks with similar odds to these, about six of them would be expected to be warmer than average over these areas, while about four years would be cooler.
The chances of receiving cooler or warmer than normal daytime temperatures for February to April is roughly equal (i.e., close to 50%) over most of the country.
The chances that the average minimum temperature for February to April will exceed the long-term median are greater than 60% over most of Tasmania, eastern Victoria, the Mid North Coast of NSW and the western and southern coastlines of WA.
The chances of receiving cooler or warmer than normal night-time temperatures for February to April is roughly equal (i.e., close to 50%) over most of the country.
The El Niño-Southern Oscillation (ENSO) remains neutral, with the majority of atmospheric and oceanic indicators close to their long-term average. Dynamical models surveyed by the Bureau suggest ENSO-neutral conditions are likely to persist at least for the next three months.
Oceans surrounding Australia are also expected to remain close to their 1981-2010 average. Atmospheric pressures may be below average over some southern areas.
