The Logan region can expect hotter than average nights and wetter than average days during Spring.
In its 2020 Spring Outlook, the Bureau of Meteorology says rain is on the horizon for most of the country.
And while warmer days are tipped for the northern half of the state, areas such as Logan can expect to need their umbrellas due to “the increased likelihood of a La Nina event”.
Winter was one of the 10 warmest winters on average in Southeast Queensland with the mean minimum temperature more than a degree above average.
The Bureau’s Manager of Climate Operations Dr Andrew Watkins said the outlook was being largely driven by changes in sea surface temperatures in the tropical Pacific and Indian oceans.
“Most long-range forecasts analysed by the Bureau, including from our own climate model, are indicating a La Niña could develop in the spring, which typically results in above-average winter-spring rainfall for Australia, particularly across eastern, central and northern regions.
“A La Niña also typically brings cooler and cloudier days, more tropical cyclones, and an earlier onset of the first rains of the northern wet season.”
Dr Watkins said spring was typically a time of year when outlook models had a higher reliability.
“At this time of year, we start to see some of our main climate drivers locking in, which gives more certainty about what our weather patterns will be like in the coming months,” he said.
“We’re starting to see that in the Pacific with a La Niña beginning to take shape, and we are also seeing some changes in the Indian Ocean, which may also boost the chance of rain during spring.”
Dr Watkins said the recent winter period is likely to be one of the warmest on record, with above average temperatures particularly prevalent in Queensland.
He also said that while the start to winter was very dry, August was the first wetter-then-average August since 2016.
