The mid north coast of NSW is affected by droughts brought about by this weather patterns. The last big drought lead to a few cattle on my parents farm dying from lack of fodder leading to weakness and getting stuck in mud around dried up dams. We had to put them down. I think it was in the summer of 91.
In relation to winds, I think we get stronger seabreezes during El Nino years. The seawater is cooler and the land is warmer leading to stronger temperature differences between land and sea.
However during the El Nino cycle the East-West trade winds across the Pacific Ocean weaken so that would affect the strength of the wind.
So in the end it probably means no wind on the weekend.

Feel free to correct me as I'm not a meterologist.
