The Lowdown
Alright, folks. Rusty here. Let’s break down the next couple of weeks for Pennington Bay.
We’re starting off a bit slow, with some messy conditions, but there’s some real firepower coming later on. The first few days are a bit of a washout, but don’t lose hope.
Water temperature is about normal for this time of year, so nothing to report there.
For the first few days, through the end of July and into the 1st of August, the wind is all over the place. We’ve got a bit of a south swell coming in, but the wind is either onshore or cross-offshore with a strong northerly breeze. Waves are around 5ft to 6ft, but the quality is poor. The combined energy is moderate to strong (1055 to 2005), but it’s not working for us.
The 2nd and 3rd of August are a total write-off. Strong cross and onshore winds, rain, and poor surf. Don’t even bother.
Now, things start to turn around on the 4th of August. Tuesday morning and afternoon we get glassy conditions with a light south wind. The swell drops to a clean 4ft in the morning and 3ft in the afternoon, with a period of 10 to 15 seconds. The combined energy is moderate (675 to 786), but the wind is the key: glassy. This is a solid pick for a sneaky session.
The real standout is the 6th of August. Thursday afternoon. We’ve got a clean, 6ft south swell at 16 seconds, with a light cross-offshore breeze from the ENE. The combined energy is strong (1446), and the report says it’s excellent for experienced surfers. This is the best of the first week. The swell direction is perfect for this break.
The 7th of August, Friday, is also a big one. It’s bigger, with 8ft in the morning and 8ft in the afternoon, coming from the south at 15 to 16 seconds. The wind is offshore from the NNE at 12 mph. This is expert territory – the combined energy is very strong (3182 and 2405). If you’re up for it, this is a heavy session.
After that, the wind picks up again on the 8th and 9th, making things tricky. The 9th has a near-gale offshore wind, which is just too hard to paddle into.
Next week, we have another potential cracker. On the 12th of August, Wednesday morning, it’s glassy again with a 7ft south-southwest swell at a very long 19 seconds. The combined energy is massive (5219). This is a serious groundswell, and it’s going to be breaking a bit straight at the beach, but with that offshore wind and glassy conditions, the points and reefs will be magic. This is the one to circle on your calendar.
The 13th and 14th of August stay big, with 8ft swell, but the wind shifts cross-shore and cross-offshore, so it’s a bit less clean.
So, to sum it up: the best on offer is Thursday the 6th of August afternoon for a clean, solid session, and Wednesday the 12th of August morning for a true, long-period groundswell with glassy winds. Don’t sleep on the 4th of August either, for a clean, smaller day.
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.
