The BoM has released its updated 2019 Autumn Outlook, showing a high chance of drier than average conditions for most of the country's east and warmer than average conditions for the entire country.

It comes on the back of what will be Australia's warmest summer on record and a long list of record-breaking days.

Among those was the wettest day in February at Yarras, Mount Seaview, west of Port Macquarie where 165.6mm fell on the region on February 22. It also claimed the record for the most rainfall across the state for February with 285.8mm.

At the other end of the scale, Port Macquarie recorded its lowest rainfall reading for February in 23 years with just 48.2mm. On average, the region should expect around 156mm.

The Bureau's manager of long-range forecasting Dr Andrew Watkins admitted the outlook wasn't the news many would be wanting to hear.

"It won't come as a surprise to many that this summer will be our warmest on record, but apart from parts of northern Queensland, many locations fell short of their summer rainfall averages too," Dr Watkins said.

"Unfortunately, the outlook isn't giving a strong indication that we'll see above average rainfall in many areas over the autumn period. The only exception is for parts of inland Western Australia.

"Autumn is obviously a critical time of year for the agriculture sector in parts of the country. It's important to remember that despite what the outlook is suggesting, individual heavy rainfall events are always possible, and people should stay up to date with the latest seven-day forecast and warnings for their area."

The outlooks also show a strong chance of warmer than average conditions continuing into and throughout autumn.

The recent summer period was Australia's warmest on record and among the top ten driest on record.

Australia experienced a range of severe weather including floods, bushfires and ongoing drought, but it was a persistent period of significant heat during December and January that headlined the past three months.

Bureau climatologist Dr Lynette Bettio said the heatwave events during December and January played a major role in the recent summer being Australia's warmest on record.

"The heat we saw this summer was unprecedented. While the final numbers are yet to be analysed, we know it will be the warmest on record for Australia as a whole, and many individual locations will have broken summer heat records as well," Dr Bettio said.

"There was a noticeable absence of strong cold fronts that would normally bring relief during summer. A lot of this was caused by persistent high pressure systems sitting over the Tasman Sea that was blocking those fronts from impacting the south of the country, especially during January.

"Rainfall was also well below average for many places, apart from areas in northern Queensland, where we saw a significant rain event during late January to early February."
