The Lowdown
Right then, let’s have a look at what’s on the cards for Lyall Bay over the next couple of weeks.
Honestly, mate, it’s a bit of a mixed bag to start with. The first few days are pretty grim, with poor conditions and not much to get excited about. We’ve got a long wait before anything really good shows up.
The first real chance of a decent wave isn’t until Sunday the 13th of September. That morning, the stars nearly align. The swell is a solid 7 ft from the S, with a period of 13 seconds – that’s some proper groundswell energy pushing in (1499). The wind is glassy, completely off the water, so it’s going to be as clean as it gets. This is definitely the standout of the whole forecast period, but it’s a serious paddle. Over 8 ft and it’s experts only, so this 7 ft is right on the edge for beginners. It’s a big, powerful wave for those who can handle it. The water temp is sitting at 57°, which is a touch warmer than normal for this time of year.
After that, the tail end of the week and into the next looks like the most consistent run. The morning of Monday the 14th has a nice 5 ft S swell (710) with a moderate offshore breeze from the NNW, making for clean, fun waves. The afternoon drops a touch to 5 ft (483) with gentler offshore winds – a good, long session on the cards.
The pattern then gets messy again. We get a few days of strong offshore winds, which clean things up, but the swell gets small and the wind is howling, making it hard to paddle into anything. The period on the 15th and 16th is mixed, with some short-period junk in there.
The second week looks less promising overall. There’s a few mornings with tiny, clean waves but nothing with any real punch. The 19th of September sees a 10 ft SSW swell (896) hit, but it’s short-period (7 seconds) and the wind is offshore, which is a bit of a wild card. That size is strictly for the experienced crew, and the short period means it’ll be a bit walled-up and messy.
From the 20th onwards, it’s a lot of marginal or poor surf. The 23rd has a glassy morning with a tiny 1 ft, and the 24th morning has a 7 ft S swell (389) but with a short period and cross-offshore winds that might clean it up a bit. It’s not a write-off, but it’s far from the standout Sunday.
So, to sum it up: if you’re an experienced surfer, keep your eyes on Sunday the 13th of September. That’s your best bet. The Monday and Tuesday after that are good for a solid session, but the rest of the window is mostly a waiting game. The break is inconsistent and a bit of a fickle spot, so a blank run like this isn’t unusual. Stay tuned.

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.
