The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Lyall Bay over the next couple of weeks.
Right off the bat, the start of the period is a bit of a write-off. We’ve got heavy rain and a strong cross-onshore wind hammering the bay on Monday morning, with a lumpy 7ft SSE swell that’s just not gonna be any fun. That poor condition hangs around through Monday afternoon and into Tuesday, with the swell dropping but the wind staying messy. There’s a bit of a gap here – nothing worth paddling out for until Wednesday morning.
Wednesday the 9th looks like our first real chance. It’s small – only 2ft from the ESE – but the wind goes offshore from the NNE, and it’s clean. The combined swell energy is weak (71), so it’s not gonna be a day for big moves, but for a beginner-friendly spot like Lyall Bay, the conditions are about as good as you could hope for. Wednesday afternoon the wind swings offshore again but gets stronger, making it a bit harder.
Thursday the 10th is a no-go. Friday the 11th though, now that’s interesting. The morning shows some promise with a 6ft S swell and clean conditions, but it’s a bit lumpy early. By Friday afternoon, we’ve got a clean 5ft SSW swell with moderate offshore wind from the north. The combined energy is moderate (430). It’s not huge, but the wind is right, and it’ll be surfable. That’s one of the better windows.
Now, Saturday the 12th – hold onto your board. The morning is a no, but Saturday afternoon sees a massive 12ft S swell with a 13-second period and clean offshore wind. The combined energy is very strong (4374). This is for experienced surfers only. The wave heights and energy are extreme for Lyall Bay, and it’s gonna be heavy. Same story continues into Sunday the 13th, with a 10ft S swell, long 14-second period, and strong energy (4307). These are the standout days for the experts, but it’s too big for most.
Monday the 14th is still solid, with a 7ft S swell and offshore wind in the morning, though the energy is dropping (1487). It’s still good for stronger surfers. After that, the swell fades fast. Tuesday the 15th is windy and messy, and from Wednesday the 16th all the way through to the end of the forecast, it’s mostly small, weak, and wind-affected. There’s a long stretch of flat or poor conditions from the middle of the second week onward.
Best on offer? Saturday afternoon the 12th and Sunday the 13th for the big-wave crew, with that huge S groundswell and clean offshore winds. For the average surfer, Friday afternoon the 11th is your best bet – clean, moderate swell, and much more manageable.
Water temp is about average for this time of year, nothing unusual to report.
That’s the story for Lyall Bay. Stay safe out there.
Rusty.

Information about the Lyall Bay Surf forecast
The above surf forecast table for Lyall Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lyall Bay can be found by selecting the local surf guide option on the grey menu. Our Lyall 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 (Lyall 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 Lyall 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.
Lyall Bay is 6 km (4 miles) from the city of Wellington. If you plan a holiday in Wellington, look for hotels and other accommodation in Wellington. Wellington has rooms for a wide range of budgets as well as car hire and transport links.
