Alright, Rusty here. Let’s have a look at what’s on offer.

To be straight with you, the next two weeks are a bit of a mixed bag. The action starts on Sunday the 12th, but don’t get your hopes up too high just yet. The first few days are looking pretty marginal – the swell is short period and the winds are a bit messy. The best of the whole run looks like it’ll be Saturday the 18th which is a solid week and a half away.

The water is sitting right about average for this time of year, so nothing weird going on with the temp.

Sunday 12th kicks off with some small, weak swell. The morning has a 3 ft from the SSW, but it’s a cross-on breeze and the energy is moderate (597). It’s not really a session you’d paddle out for. The afternoon sees a jump in size to 7 ft from the NW, but the period is a short 8 seconds and the wind is straight onshore. It’s messy.

Monday 13th and Tuesday 14th are more of the same. Waist to chest high NW windswell, period around 7 to 8 seconds, and that cross-on wind doesn’t let up. The break is inconsistent anyway, so it's really not the time to be burning petrol.

Wednesday 15th gets a bit bigger. The afternoon has 8 ft from the NW (957 energy), but that’s getting into the too-big-for-beginners territory, and with the short period and cross-on breeze, it’s going to be a bumpy, walled-up mess. Not great for paddle surfing.

Thursday 16th is a day where the size gets serious. The afternoon pushes 10 ft from the NW with a moderate energy (1664), but the wind is still cross-on. The swell is too big for this break, and the period is only 8 seconds. This is a setup that would be more interesting for kite surfing than a traditional paddle session.

Friday 17th and Saturday 18th are where it gets interesting. The swell drops a bit, but the period stretches to 9 seconds. Friday still has a bit of wind on it, but Saturday the 18th is the real standout. The morning has some clouds, but the afternoon turns glassy – wind is 3 mph from the W and glassy. You’ve got a solid 5 ft from the NW (1119 energy) and it’s clean. That’s the best the window has to offer. The break is inconsistent, so you’ll have to be patient, but when that set rolls through, it’ll be worth it.

Sunday 19th through to Wednesday 22nd sees a big drop in size. The swell goes back to under 3 ft, but the period gets long – 15 to 17 seconds. That’s a groundswell, but it’s small. The winds are mostly light or cross-on, so it’s not going to be terrible, just small. The long period means it’s better suited to a point or reef, but here it’ll just be small and clean on the sets.

Thursday 22nd afternoon picks up again with a 6 ft NW swell (8 seconds), and the wind goes onshore. Friday 23rd and Saturday 24th build back up. Saturday 24th afternoon hits 10 ft from the NW (1639 energy) – again, too big for this break and the wind is cross-on. That pattern repeats into Sunday 26th with 10 ft and a moderate breeze making it choppy.

The long-range stuff from the 23rd onward is a bit uncertain, but it looks like more of the same – waves, but windy and too big for the spot. The best and most reliable surf in the whole 16 days is that glassy Saturday afternoon on the 18th. That’s the one to circle.

Rusty.

Information about the Seaside Creek Surf forecast

The above surf forecast table for Seaside Creek provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Seaside Creek can be found by selecting the local surf guide option on the grey menu. Our Seaside Creek surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Seaside Creek) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Seaside Creek may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
