Following all the kerfuffle at the Surf Ranch event, the Wozzle will be hoping the internet shifts its attention from judging hoopla to the actual surfing at the next event in El Salvador. It may even happen before the first hooter blows with good waves due through the lead up period.

The waiting period kicks off next Friday, the 9th of June. The start time translating to midnight Friday Australian Eastern time - only the most ardent Aussie fans need apply for this one.

La Libertad, the boulder strewn right-hand point where competition is being held, has an enormous swell window. Ostensibly it's open to the whole Southern Pacific, with SW to S/SW groundswells being the most favourable for producing fast, walled-out rights. Too west and it's slow, too south and the sections will get ahead of the surfer - as we saw through some days of competition last year.

To open affairs, a strong mid-latitude low that's currently projecting towards Chile will generate a moderate to large S/SW groundswell for the first half of next week, providing a couple of great warm-up sessions.

For the opening day of the waiting period, a smaller, inconsistent background swell from south-east of New Zealand looks to provide infrequent 3-4ft sets, with a better, more S/SW swell due to arrive into the second day of the waiting period.

This swell will be generated by another mid-latitude low forming west of Chile, projecting strong to gale-force S/SW winds up through El Salvador's southern swell window - see image below. More consistent 4ft+ waves should be seen from this source along with light morning offshore winds and manageable sea breezes from the south-southwest, coming from behind the wave.

Now, starting later this weekend, the recent purple patch of Southern Ocean frontal activity under Australia will transition to the east, with a great polar frontal progression due to develop south-east of New Zealand. This will then continue eastwards while broadening in scope, generating a prolonged yet inconsistent S/SW groundswell event.

The inconsistency is a product of it forming 10,000kms away from El Salvador. The travel time will be 9-10 days, with it due to arrive towards the end of the waiting period.

That will be through the middle to end of the following week, with the long-period forerunners due to arrive later Tuesday El Salvador time, building further Wednesday, peaking into the afternoon and then easing slowly Thursday.

Infrequent but strong sets to 4-5ft+ should develop through Wednesday, easing from a similar size on Thursday. Due to the broadening nature of the system, reinforcing pulses of southerly groundswell from the same system are due into the end of the waiting period.

At that point, we're looking too far away to have real confidence in the wave size, yet it's enough to know that the trends are positive therefore the outlook is too. We'll hone in on wave size at the end of the waiting period as we get closer.

Local winds look favourable through most of the period, though a trough may interfere with things Wednesday week, but this is too far away to have any confidence.

We'll continue to monitor the South Pacific over the coming fortnight for any major upgrades to the swell potential.
