The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for Lighthouse Reef. We’ve got a tricky start with a lot of flat spells, but there’s a couple of real windows that’ll get the heart pumping if you’re patient.
Right off the bat, we kick off Wednesday the 2nd of September. It’s not massive, but it’s the best we’ve got for a while. We’re looking at a chest-high 3ft swell from the SE with a very long 15-second period, which is that proper groundswell energy. The combined energy is a solid moderate 468, and the wind is a gentle offshore from the WNW. That’s clean, glassy conditions with just a light breeze. The water temp is sitting at 51°F, which is a touch warmer than normal for this time of year, so it’s not a bad time for a session. The break is inconsistent and only for advanced crew, so don’t expect a circus in the water, though it can get crowded sometimes.
That window closes fast. Wednesday afternoon drops off, and then from Thursday the 3rd all the way through to Sunday the 13th of September, it’s grim. That’s a solid ten-day stretch where the swell vanishes, or the wind is just messy. You’ll see a lot of tiny, weak energy readings – most days are under 100, with many below 50 – and the wave comments are all terrible. Even when there’s a bit of swell, like Monday the 7th with 4ft, the wind is fresh cross-shore and the period is short at 8 seconds. It’s just lumpy, junky stuff. Not worth a paddle.
Things finally start to look up on Monday the 14th of September. The morning shows a 5ft SE swell with a 12-second period and moderate energy in the 549 range. Wind is light and cross-off from the NNW, keeping it clean. That afternoon, the swell holds at 5ft, period drops a tick to 11 seconds, but the energy is still solid at 496 and the wind is a light cross-off again. Conditions look good here.
Now, the standout – and I mean the real standout – is Tuesday the 15th of September morning. This is the one. The combined energy rockets to a whopping 1406 (very strong), driven by an 8ft swell from the SSE with a 10-second period. That’s overhead plus, and the wind is a gentle offshore from the WSW. This is going to be powerful, clean, and very hollow. The data says it’s excellent for experienced surfers only, and I agree – anything over 8ft is expert territory. If you’re not solid, give this one a miss. It’s a beach and reef setup, and with that much juice, it could be a bit unruly, but for the strong paddler, it’s the session of the forecast period. The afternoon gets messy with strong onshore winds, so make the most of the morning.
After that, Wednesday the 16th morning offers a more manageable 4ft from the SE with good light offshore winds and clean faces, but the afternoon and Thursday the 17th get spoiled by light cross-shore breezes making things a bit bumpy.
So, bottom line: the first ten days are almost a write-off. Don’t bother until the 14th, and definitely lock in that Tuesday the 15th morning if you’ve got the skill. That’s the only true standout.
Stay safe out there.
Rusty.

Information about the Lighthouse Reef Surf forecast
The above surf forecast table for Lighthouse Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lighthouse Reef can be found by selecting the local surf guide option on the grey menu. Our Lighthouse Reef 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 (Lighthouse Reef) 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 Lighthouse Reef 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.
Lighthouse Reef is 4 km (2 miles) from the city of Timaru. If you plan a holiday in Canterbury, look for hotels and other accommodation in Timaru. Timaru has rooms for a wide range of budgets as well as car hire and transport links.
