The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Pennington Bay over the next couple of weeks.

Right off the bat, we’ve got a bit of a flat, messy start. Monday the 7th is a write-off with onshore wind and weak, choppy junk. But hold tight, because this stretch of coast is about to wake up.

The real story starts to build on Tuesday the 8th. Tuesday morning is a stunner. We’ve got a solid 6ft long-period groundswell rolling in from the south, and the wind is dead glass. The water is sitting at 59°F, which is about average for the time of year. The combined energy is a beefy 2171 (moderate). This is clean, glassy surf for the experienced crew. The afternoon gets blown out, so make the most of the morning session.

The swell keeps building, and by Wednesday the 9th we’re looking at a huge 13ft SSW swell with a very long 19-second period. That’s serious energy – 20391 (very strong). But the wind is a fresh cross-onshore, and honestly, for a break like this, that’s just too much juice. This is for experts only, and even then, the wind is going to make it lumpy and tough. Probably looks better for the kite surfers that day.

We see a bit of a drop on Thursday the 10th, but it’s still a solid 10ft with a side-shore wind. It’s a bit messy, so it’s marginal.

Now, here’s where things get really good. Friday the 11th and Saturday the 12th are the true standouts of the first week. Friday delivers a clean 7ft S swell with a light cross-offshore breeze. The period is 14 to 16 seconds, so the waves have real shape. The combined energy is 1797 to 2214 (moderate). It’s clean, consistent, and just right. Saturday offers a 5ft S swell with a clean offshore wind of 12 mph, making for a ripping morning session. The combined energy is 1178 (moderate). The crowds are listed as "often" here, so expect plenty of company if you’re paddling out.

The second week has a few flickers of hope. Sunday the 13th has some fun little 4ft to 3ft waves with offshore wind, but it’s small. The real potential comes back strongly on Saturday the 20th and Sunday the 21st. On the 20th, we have a 7ft swell with a glassy offshore wind – that’s a beautiful, clean day for the experienced. The 21st sees a very large 10ft to 12ft SSW swell with a cross-offshore breeze. The combined energy is 8629 to 9950 (very strong). This is a promising, long-range call for the bigger-wave surfers, but remember, it’s a week and a half out, so keep an eye on it. The 22nd also looks excellent for a Tuesday morning with a 10ft S swell and a clean offshore wind.

Overall, you’ve got a solid run of surf here. The best of the best is the glassy morning of Tuesday the 8th and the clean, well-shaped Friday the 11th. Don’t sleep on them.

Rusty.

Information about the Pennington Bay Surf forecast

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