The Lowdown
Alright, let’s talk Lyall Bay in feet.
Water temp is about 55°F, dead average for the season.
Friday the 7th of August kicks off with a 5ft south swell, 15 second period – that’s proper groundswell, energy reading 1485. But the wind is a cross-off from the NNW at 22 mph, and the tide is no friend. It’s a frustrating start.
Saturday the 8th, the swell drops to 5ft, still south, period down to 11 seconds. Saturday afternoon the wind turns offshore from the north at 19 mph, and the energy is 462. It’s a bit better, but still just marginal.
Sunday the 9th is a mess – near gale offshore at 34 mph, swell only 4ft. Not worth it.
Monday the 10th is onshore and lumpy.
Best early window is Tuesday the 11th of August in the afternoon. The swell is 5ft from the SSE, short period at 8 seconds, energy 350, but the wind is glassy – dead calm. That’s clean, clean, clean. It’s your best shot in the first week.
Then the waves just disappear. From Wednesday the 12th all the way through, the energy drops to 76, 64, 34, 32, 21, 50 – it’s basically flat. A long dead stretch.
Sunday the 16th of August shows a massive 13ft south swell with 3114 energy. That’s far too big for Lyall Bay – it’s a beginner spot that rarely gets good, and that’s a danger zone. Same for the 19th of August – another 13ft pulse. Only for experts, and even then, not smart.
The other option is Friday the 21st of August. The swell is 7ft from the south, period 11 seconds, energy 1037. The wind is offshore from the north at 16 mph in the afternoon. That’s clean, and the direction suits the break. It’s the best of the far-out calls, but it’s two weeks away, so keep your expectations in check.
So, Tuesday afternoon the 11th is the standout, and maybe the 21st if you’re patient. Otherwise, it’s a long wait.

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.
