A wet summer ahead with La Nina declared
LA NINA has officially been declared this summer and it will have impacts on our farmers.
While the cooler temperatures may not be good for cotton growers, the rain will be good for avocado growers to get through a hot March and February.
Mt Binga avocado grower Kaylea Paulger said rain was good for avocados in the hotter months.
"Generally for us it's good during the hotter months, it all depends on the amount we get, if we're looking at hundreds and hundreds of millimeters it's not a good thing,” she said.
"In the low lying country the trees will get water logged, but if we have fairly good rain it mean the crop will be good.”
Avocado seeds set in September and are harvested at the end of May, so getting enough rain over summer months is crucial for the crop.
"We really need good summer rain, if we got rain every three or four days, that would be ideal,” she said.
"As long as it's not a massive amount.
"Our main time for water stress is January and February, if it rains early December and January enough to fill that soil profile we will be right to the end of February we get that big heat and in March it can be quite hot.”
For those with trees at home Ms Paulger said people want to be sure their trees are not going to get waterlogged.
"If they are grown on a mound they will generally be alright,” she said
"The trees will die if they are waterlogged between 12 and 24 hours they die in the root bone.”
La Nina means summer will be wet with more cloud cover and cooler temperatures. La Nina occurs when equatorial trade winds become stronger, changing ocean surface temperatures.
The warming of the ocean temperatures in the western Pacific means the areas becomes more favourable to rising air, cloud development and rainfall.
As a result heavy rain can occur to the north of Australia.
Unlike El Nino years, the impacts of La Nina often continue into the warm months. In eastern Australia, the average December - March rainfall during La Nina years is 20 per cent higher than the long-term average, with eight of the ten wettest such periods occurring during La Nina years.
