Alright, Rusty here. Let’s have a look at what’s shaping up for Pennington Bay over the next couple of weeks.
The week kicks off with some solid, clean swell. Monday morning sees a solid 6 ft south swell with a long 14-second period pushing in, and the wind is a light cross-off. The water temp is sitting about average for this time of year, so nothing unusual there. The combined energy is pumping at 1315, so there's proper power in the water. The waves will be well-shaped and clean, and the bay is fairly exposed to that south direction, so it’s set up nicely. Monday afternoon backs off a touch to 5 ft, but it’s still clean with that cross-off breeze.
The standout of the whole forecast is Wednesday, 8th July. We get a jump in size to 7 ft from the south, with an 18-second period that’s really pushing energy through – the combined energy hits a whopping 2964. Wind is light and cross-off in the morning, switching to a light offshore by the afternoon. That’s about as good as it gets at Pennington Bay. The waves will be chunky, clean, and have proper power – this is for experienced surfers only. Crowds are often here, so expect a few locals out.
After that, Thursday 9th July is still very good with a gentle offshore breeze, but the swell drops to 4 ft to 4 ft. The combined energy is moderate, sitting in the 700-800 range. It’ll be clean and cruisy.
Sadly, things go downhill from the weekend. Friday 10th July sees the wind picking up, and it stays messy through the weekend and into the next week. Saturday 11th July has strong breeze and poor conditions, and Sunday 12th July sees a 8 ft to 10 ft south swell, but the wind is strong cross-onshore, making for ugly, messy surf. The wave energy is high (over 3800), but with that wind, it’s a write-off for paddling – probably more of a kite day.
The following week has a few blips of hope. Thursday 16th July morning and afternoon have a gentle offshore wind with a 5 ft south swell. The period is a solid 14 seconds and the combined energy is moderate (953 and 809). The surf will be clean and rideable – a nice little window in an otherwise average week.
The final few days of the forecast from 17th July onward are quite poor, with strong winds and cross-onshore conditions, or messy, choppy waves. There’s no real standout in that second week besides Thursday.
Overall, the best bet is Wednesday 8th July – get on it if you can handle the size. Thursday is your backup for a cleaner, smaller session.

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.
