The Lowdown
Alright, it’s been a bit of a slow start here at Lyall Bay. The first few days are a write-off with howling southerly winds and a big, unruly swell just getting chopped up. Saturday the 1st of August is a total no-go – that 15 ft SSW swell is a mess under a 45 km/h southerly (combined energy of 4069) – that’s just for the big dogs or the kite surfers. We’ve got to wait until Sunday the 2nd for the first real chance.
That Sunday morning, the wind swings around to the north and goes offshore. It’s a solid 7 ft S swell with an 11-second period (combined energy of 1231). The water temp is sitting at 55°, which is about average for this time of year. It’s a clean, fun-sized wave, but remember Lyall Bay is pretty inconsistent, so you’ll be waiting for your sets. It’s the best on offer for the weekend, but it’s not a world-beater.
Monday the 3rd still has some decent offshore energy in the afternoon, with a 4 ft SSW swell and a nice 12-second period, but the wind is light and cross-shore in the morning. It’s a bit of a mixed bag.
The real standout is shaping up for Thursday the 6th of August. The morning is looking glassy with an ENE breeze at just 5 km/h, and there’s a clean 6 ft SSE swell with an 11-second period (combined energy of 1217). That’s going to be smooth and clean, perfect for a long session. The afternoon is even better – dead calm, glassy conditions, with a 5 ft SSE swell. That’s your pick of the whole first week.
Then Friday the 7th of August is for the experienced crew. We’ve got a 8 ft S swell with a very long 16-second period in the morning (combined energy of 3824). That’s a proper groundswell. The offshore northerly wind will keep it clean, but at that size and with that long period, it’s only for the experts. It’s going to be powerful and a bit of a paddle out, but the waves will be well-shaped.
After that, the surf drops off and the winds go onshore again. There’s a long gap of poor conditions from the 10th right through to the 13th of August. It’s just small, choppy, and messy. Combined energy dips down to as low as 32 during that spell.
We get a little flicker of life on Friday the 14th of August – a 8 ft SSE swell with a fresh offshore northerly wind (combined energy of 627). It’s a moderate swell with a short 8-second period, so it’ll be a bit lumpy, but it’s a clean option for a late-week surf. Not a standout, but it’s rideable.
The last day of the forecast, Sunday the 16th of August, is a small, weak, onshore mess again. Nothing to get excited about.
So, the main takeaway: if you’ve got a flexible schedule, hold out for Thursday the 6th of August. That glassy, clean 6 ft SSE swell is the best of the lot. If you’re after something bigger and you’ve got the skill, Friday the 7th of August is your window.

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.
