Recap

Early light winds yesterday before conditions deteriorated with a trough and onshore change across all locations. The swell was down on Monday's pulse, while this morning we've got some new reinforcing energy but with less than ideal winds. Semi-protected spots were best in the South West while Perth and Mandurah remained onshore.

This week and weekend (Jan 12 - 15)

Tomorrow morning will be the pick of the end of the week, with conditions expected to improve across exposed spots in the South West with a light E/SE breeze and easing 4ft sets across the magnets.

Perth and Mandurah will be tiny and offer less favourable S/SE winds before sea breezes kick in.

A trough will unfortunately see S tending S/SW winds on Friday as the swell eased further, a lay day.

Moving into the weekend, a small mid-period SW swell is due to build through Saturday though to no major size, generated by a weak fetch of W'ly winds moving through our swell window today.

Strong SE winds will create tricky conditions as the swell builds to 3-4ft in the South West (tiny in Perth and Mandurah). Sunday will be cleaner with a gusty E/SE offshore but small 3-4ft of swell persisting on the coast.

Looking at early next week, fun pulses of SW swell are due across the state, the first for Monday being mid-period energy ahead of some slightly stronger, larger groundswell Tuesday.

The first pulse will be generated by a fetch of pre-frontal W/NW winds around the northern flank of a broad polar low, while trailing strong to gale-force W/SW winds should generate a better groundswell for Tuesday.

Monday's swell should come in at 3-5ft across the South West, tiny in Perth and Mandurah with Tuesday's offering better 6ft sets in the South West, 2ft Mandurah and 1-2ft in Perth.

Winds will unfortunately be poor Sunday as a trough brings strong S/SE winds on Monday, better Tuesday morning and shifting SE, gusty through the morning.

Wednesday will become even cleaner with a gusty E/SE offshore but with smaller, easing surf.

Longer term there's nothing too major expected so try and pencil a surf in around next Tuesday. See you back here Friday.
