Best Days: Saturday protected spots, Sunday, most mornings next week (Wednesday the pick)


Excellent conditions across the South West yesterday morning with a large new swell to 6-8ft with offshore winds. Mandurah was great with 2-3ft sets, while Perth kicked to 2ft.

This morning the swell was smaller and back to 1-2ft around Mandurah and Perth, while 5-6ft sets were breaking on the exposed reefs around Margs.

This weekend and next week (Mar 22 – 28)

Into this afternoon/evening a new pulse of W/SW groundswell is due, the first and smallest of two expected in the next 24 hours, with a much larger pulse for tomorrow.

These swells have been generated by back to back frontal systems, with the second front moving over the active sea state produced by the initial system, resulting in more size.

Tomorrow's swell should be consistent and out of the W/SW, coming in at 8-10ft across the South West, 3ft in Mandurah and 2-3ft around Perth. A drop in size should be seen later in the day, easing back further Sunday from the 6ft and 2ft+ range respectively.

Winds are still expected to be from the S/SE tomorrow (E/SE Perth), strengthening through the day which will favour protected breaks.

Slightly better SE breezes are then expected into Sunday morning, S/SE into the afternoon.

Monday will be smaller again with SE breezes, possibly E/SE if we're lucky.

Through Tuesday and Wednesday some small SW groundswell pulses are expected across the South West, generated by relatively weak and unconsolidated polar storm activity over the weekend.

The first increase for Tuesday looks to come in around 4ft across the South West (tiny in Perth), while a slightly longer-period swell is due late in the day and Wednesday morning to 4-5ft.

Favourable SE-E/SE offshores are due Tuesday, while Wednesday looks excellent with a light to moderate and straight E'ly breeze ahead of mid-afternoon onshores.

Longer term there's still nothing major showing on the charts, therefore if you're looking for size, try and surf over the coming days. Have a great weekend!
