The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for National Park.
Overall, the next 16 days are a bit of a mixed bag. We’re looking at a weak start, a solid pulse mid-period, but then it gets real inconsistent again later. Nothing mind-blowing, but there’s a day or two that’ll get you frothing.
First up, we’re looking at Saturday the 15th, but it’s a total flop. Swell is barely there at 1 feet from the east with a weak period of 9 seconds. The wave energy is weak (28). The wind is cross-off but strong at 16 mph, but with no waves to work with, it’s a write-off.
The real action starts to build on the 16th. Sunday the 16th morning sees the swell jump to 6 feet from the southeast, but with a short period of only 6 seconds. It’s got moderate energy (317), but the wind is cross-off and a bit punchy at 16 mph. It’s surfable but pretty ordinary. The afternoon cleans up nicely with fresh offshore wind at 19 mph from the SSE on that 6 feet SE swell, but the short period still has it a bit unruly.
Now, here’s the standout window. Monday the 17th and Tuesday the 18th are your best bets. We’ve got a solid southeast swell pumping in. Monday morning offers 7 feet from the ESE with a 7-second period and strong energy (456). The wind is offshore from the SE at 19 mph, keeping it clean. It’s a bit heavy for beginners at this size. Tuesday the 18th is the pick of the pick. The morning still has 7 feet ESE swell (512 energy), but by Tuesday afternoon it drops to 7 feet from the ESE, period stretches to 8 seconds, and the energy is very strong (525). The wind is a solid offshore from the SE at 16 mph. This is where you get proper clean, powerful point-break waves. The direction (ESE) matches up well with what this spot likes (ENE). It’s at the top end of intermediate, but if you know what you’re doing, you’ll be in for a treat. National Park is a point break, and with that longer-period groundswell, it’ll set up nicely.
Wednesday the 19th still has some leftover energy. Morning brings 6 feet ESE swell (485 energy) with light offshore wind at 12 mph. Not as good as Tuesday, but still fun. By the afternoon it drops to 4 feet, and the energy fades.
From Thursday the 20th through to the 26th, we’re back to small, weak surf. Mostly 1 feet to 4 feet, with periods all over the place. Wind is mostly cross-off or light, but the wave energy is low (down to 14 on the 26th afternoon). There’s a glimpse of something on Thursday the 20th afternoon with 3 feet SE swell (324 energy) and good offshore wind, but it’s marginal.
There’s a new pulse on the 28th. Friday the 28th morning shows 7 feet from the east (8-second period) with very strong energy (486), but the wind is onshore from the NNW at just 6 mph, making it messy. By afternoon, it’s a cross-onshore chop-fest. Not great for surfing, might be interesting for kite surfers.
The tail end of the forecast, Sunday the 30th, is worth mentioning. The morning is glassy with a clean 3 feet ESE swell and a longer period of 10 seconds. The energy is moderate (343). With the wind dead calm (glassy conditions), this could be a sneaky clean day for a small-wave fun session, but the swell is small.
So, for the two true standouts: Tuesday the 18th afternoon for the power and the clean offshore wind, and Monday the 17th as a close second. The rest is either small, windy, or just average. The water temperature is sitting at 69° for now, which is about average for this time of year.
Stay stoked, and keep an eye on those forecasts. Things can change.
Rusty.

Information about the National Park Surf forecast
The above surf forecast table for National Park provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at National Park can be found by selecting the local surf guide option on the grey menu. Our National Park 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 (National Park) 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 National Park 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.
National Park is 34 km (21 miles) from Sunshine Coast. If you plan a holiday in Sunshine Coast, look for hotels and other accommodation in Sunshine Coast. Sunshine Coast has rooms for a wide range of budgets as well as car hire and transport links.
