Surf forecast issued Thursday 26 May 2016:
Eight day outlook for Sydney:
Just a touch windy today. The fresh to gusty Northwesterly is gradually knocking down the largish surf that’s been around, While some new swell will be coming this way from a Southerly direction it will have a lot of SSW in it, which means the bigger stuff will be passing right on by. How much if any gets in will be a battle some days between fresh offshores and the size, period and direction of the swell~~~~~~~~ TG’s bestimates follow:) :
Friday: down more than today, say call it lower end of the 1-2 metre range at places that get dead South swell
Saturday: coming up in the 2-3 metre range, dead South spots
Sunday: down a bit 2, 2+ metres dead South
Monday: going down in the 1-2 metre range dead South places
Tuesday: low end of the 1-2 metre range South East, with light onshore
Wednesday: about 1 metre South East light onshore with it
Thursday: up a tad in the 1-2 metre range South East
Friday: down again to about 1 metre or so South East.

El Nino over, BoM says, so winter rain could be on the way
Updated Wed at 12:12pm
The latest El Nino cycle is over, which could lead to a wet winter, according to the Bureau of Meteorology (BoM).
Key points:
- El Nino events cause extensive warming of the Pacific Ocean
- This leads to lower-than-average rainfall and periods of higher temperatures across Australia
- El Nino events occur every three to six years
The bureau’s modelling shows ocean surface temperatures across the tropical Pacific have cooled to neutral levels over the past fortnight.
Waters beneath the surface have also cooled.
Forecaster Michael Knepp said conditions were back to neutral and the bureau was now on La Nina watch.
During La Nina events, rainfall in winter and spring is above average over northern, central and eastern Australia.
“[There’s] a greater than 50 per cent chance that we might be in La Nina conditions later in the year,” Mr Knepp said.
“That’s not a certain thing, just something to keep an eye on over the next few months.”
International climate models indicate the tropical Pacific Ocean will continue to cool.
Six of eight models suggest La Nina is likely to form during winter.
Mr Knepp said more rainfall could be expected across the region if predictions were correct, but the outlook accuracy at this time of year was low.
El Nino contributes to drought conditions
El Nino has contributed to drought conditions over the majority of Queensland. Currently, 85 per cent of Queensland is drought declared.
Queensland grazier Peter Whip said the prolonged drought had been devastating for farmers.
Mr Whip, whose property is south of Longreach, said winter rainfall was better than nothing.
“You either want a lot or none,” he said.
“It can actually do more harm than good because if we have got a little bit of dry feed from the summer rain.
“Sometimes with that winter rain, if we get 50 points, it can actually wreck the feed you’ve got.”
Rainfall deficiency across Australia
The bureau said almost the entire western half of Victoria was experiencing severe rainfall deficiency.
The rainfall deficiency in Tasmania covers much of the state.
Areas of serious to severe deficiency remain through inland Queensland and into northern New South Wales.
Large areas of South Australia and Western Australia are also experiencing serious rainfall deficiency.
