Table - best surf conditions forecast for Lighthouse Reef over the next 16 days.
The Lowdown
Alright, let's talk about Lighthouse Reef. This spot is a beach and reef setup, and it's known as an advanced wave, so keep that in mind. The water here is a touch warmer than usual for this time of year, sitting at 50°F.
The next 16 days are a real mixed bag. We've got a bit of a quiet start, but there's a proper window of opportunity that's worth circling on the calendar.
We kick things off on Thursday, the 27th of August, but don't get too excited. The wind is a messy cross-on from the northeast, and the surf is small and weak. The combined energy is a low 313, and it's just poor conditions. Friday the 28th is where it starts to get interesting. The morning brings a solid pulse of groundswell from the ENE at 8ft, but the period is short at 9 seconds. The wind is a clean cross-off from the NNW, making for good shape. The wave energy jumps up to 1238, which is strong. This is the standout session for the whole outlook. The swell is 8ft, so it's getting into expert territory, but the conditions are clean and it's a proper wave. The ENE swell direction is exactly what Lighthouse Reef likes to see. Crowds are sometimes a factor here, so keep that in mind.
Friday afternoon drops off a bit with a 3ft east swell and a glassy offshore wind, but the energy is moderate at 225. Saturday morning the 29th is tiny with a 1ft SE swell, and the rest of the weekend and into the following week is a real lull. The swell direction swings to the SSE, which is not the optimum for this spot. The energy is weak, and the wind is all over the place, with a nasty 25 mph cross-off on Sunday afternoon.
We then have a prolonged gap of poor to ordinary surf right through to the end of the first week of September. There's a small window on Tuesday morning, the 1st of September, with a 4ft SE swell, light cross-off wind, and moderate energy of 316, but it's not a standout. The rest of the first week and into the second week is mostly flat with tiny 0.7ft to 2ft waves and all the energy is weak.
Looking further out, the 5th of September has a few very ordinary small waves, and the 9th of September afternoon sees a short-period 4ft ENE swell, but it's only 7 seconds, and the energy is moderate at 192. The 11th of September shows a long-period SSE swell of 3ft with a clean offshore wind, but the energy is 334 and the swell is from the wrong direction.
So, the clear standout is the Friday morning, the 28th of August. That 8ft ENE swell with the clean cross-off wind is the best you're going to get in this 16-day window. The rest is a waiting game for the next proper swell.

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.
