The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s on the cards at Mousetraps over the next couple of weeks. This is a heavy-duty reef break for advanced surfers only, and it’s exposed to the southwest swell. The water temp is sitting around 65°, pretty much normal for this time of year, so nothing unusual to worry about on that front.

We’ve got a solid run of surf coming, but the opening weekend is a write-off. Saturday the 5th is a mess with fresh cross-onshore winds and lumpy conditions, and the wave quality is just poor. The swell energy is strong though, hitting 4439 on Saturday morning. But with those winds, you’d be better off staying home. Sunday the 6th cleans up a bit with cross-off breezes and the combined energy jumps to 4339 in the morning and a massive 6984 in the afternoon, but the surf forecast is still only marginal due to tide or conditions.

Now, Monday the 7th is where it starts to get interesting. The morning session is looking exceptional for the experienced crew. We’ve got a 12 ft swell from the SW with a very long period of 16 seconds, and only a gentle cross-off breeze. That’s clean, powerful, and the sets will have some serious push. The energy is sitting at 6307, which is strong. This is a standout session for experts.

The best of the whole window looks like Tuesday the 8th. Morning brings a 13 ft SW swell, 16-second period, and clean offshore wind from the ESE. The combined energy is a huge 8296. That is proper, groundswell-driven power. The afternoon is still excellent with 12 ft of WSW and offshore breezes. Both sessions are clean, giving you two chances at this one.

The run of clean surf continues Wednesday the 9th, with offshore winds again, 10 ft of WSW swell, and energy around 4390 in the morning. It’s a step down in size but still excellent for experienced surfers.

By Thursday the 10th, the swell drops to around 6 ft to 6 ft, and the energy drops to 1653, so it’s much smaller and weaker. The winds are cross-off to cross, and the rating drops. It’s not worth getting wet for.

Friday the 11th is a poor day with a messy 6 ft from the WSW and moderate cross-onshore chop. Then Saturday the 12th and Sunday the 13th are fully blown out with onshore gales and surf climbing up to 15 ft, but with poor conditions. Stay away.

Looking ahead to the second week, Monday the 14th morning brings another standout. A 13 ft WSW swell with a 15-second period, gentle cross-off from the SSE, and clean conditions. The energy is a massive 7390. This is a serious session for experts. The afternoon turns choppy and cross-on, so hit the morning.

Tuesday the 15th is clean again in the morning with 10 ft from the WSW, energy at 4789, and light offshore. It’s good but not a standout.

Wednesday the 16th is moderate and mixed, with cross-shore winds. Not the best.

Now, Thursday the 17th is worth a mention. Morning is clean with 10 ft from the WSW and light cross-off, energy at 4692. But the afternoon on Thursday the 17th is pure glass – light wind, 12 ft of long-period WSW swell, and the energy at 4640. That is going to be smooth, lined-up, and beautiful for the experts.

Friday the 18th turns ugly again with cross-onshore winds and choppy surf. Then the final weekend – Saturday the 19th and Sunday the 20th – sees a massive swell pulse. We’re talking 16 ft to 18 ft swells from the WSW with energy readings over 14,000 and up to 17,562. The wind is onshore and the forecast says the surf is simply too big for this break. That’s only for the absolute lunatics, and even then, it’s a danger zone.

Overall, the standouts are clear: Tuesday the 8th is the best on offer with that clean, offshore, 13 ft SW groundswell. Monday the 7th morning and Monday the 14th morning are also top-tier. For the experts, the glassy Thursday afternoon on the 17th is a gem.

Take care out there. This is a heavy break.

Rusty.

Information about the Mousetraps Surf forecast

The above surf forecast table for Mousetraps provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mousetraps can be found by selecting the local surf guide option on the grey menu. Our Mousetraps 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 (Mousetraps) 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 Mousetraps 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.
