The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Lyall Bay. We’ve got a slow start, but things look like they’ll kick into gear for the weekend.
Right now, the water’s sitting at 53°, which is a touch under 2°F cooler than usual for this time of year, so it’s a bit nippy, but nothing crazy.
The next few days are a write-off for a decent paddle. Thursday the 16th is flat with a messy cross-off wind, so don’t even bother. Friday morning the 17th is where we finally see a pulse – a 3ft groundswell from the ESE with a super long 16-second period. The wind is offshore from the NNE, so it’ll be clean. It’s a bit inconsistent though, so you’ll have to wait for the sets, but the shape should be good for a beginner-friendly wave. The energy is moderate (694).
The real standout is Saturday afternoon, the 18th. The swell jumps to 6ft from the SSW, with a very long 22-second period. That’s proper groundswell energy (3289). The wind stays offshore from the N, so it’ll be clean and lined up. This is an excellent wave, but at 6ft, it’s getting into that size where you want to be comfortable in the water. It’s not for total beginners. This is the best session on offer.
Sunday the 19th still has some size, 5ft from the SSW and a long 15-second period, with light offshore winds in the afternoon. It’s a good option, but not quite as strong as Saturday.
The following week sees a drop in size. Monday the 20th is messy with onshore wind. Tuesday the 21st has a fun 6ft SSW swell again, but it’s a bit bigger. The afternoon looks clean with a light offshore from the N, making it another good option for experienced surfers. The energy is strong (1894).
After that, we get a lull. Wednesday the 22nd to Thursday the 24th sees the swell drop right off, with small, weak waves. There’s a decent gap of poor or small surf from the 23rd to the 25th. Friday the 24th and Saturday the 25th are blown out by strong winds.
Then, towards the end of the month, Sunday the 26th afternoon brings back a clean 6ft S swell with a light cross-off wind. That’s a solid end to the forecast. The morning of the 31st of July shows a punchy 7ft SSW swell, but it’s only 8 seconds, so it’ll be a steep, dumpy wave. That’s strictly for experts.
Overall, the best bet is Saturday afternoon the 18th of July for the best combo of size, wind, and period.

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.

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.
