The Lowdown

G'day, Rusty here. Let's have a look at what Lighthouse Reef has on offer over the next couple of weeks. The region label is from the sub-region provided.

First up, it's a slow start. We're looking at Wednesday the 22nd through to Friday the 24th with pretty much nothing doing. Tiny waves in the 0.3ft to 1ft range, poor conditions, and a flat spell. That first week is a bit of a write-off for any serious paddling.

We get a little bump on Saturday the 25th morning with a 3ft swell from the south, but it's a short period of 5 seconds, so it's going to be lumpy and weak. The combined energy is weak at 115, and the conditions are just "ordinary." Not worth rushing for.

The real action starts to build from Monday the 27th. Early that morning, we see a clean 3ft east-southeast swell with a period of 13 seconds and a light offshore wind from the west. The energy is moderate at 406, and it's clean. This is where it gets interesting.

But the standout. The big standout is Tuesday the 28th. Morning session is absolute gold for the experienced crew. We've got a solid 6ft easterly swell from the east-southeast, with a long 14-second period. That's a groundswell, and paired with a light offshore from the north-northwest, it's going to be clean as a whistle. The combined energy is strong at 1303. This is an excellent surf conditions call for experienced surfers. If you can handle it, that's your morning. The afternoon will still be solid at 6ft but a bit more cross-shore, so go early.

Wednesday the 29th is also very good, with 5ft waves, same east-southeast direction, and offshore winds in the morning. Clean, plenty of energy at 623. A ripper of a session for those who missed Tuesday.

The week then slowly winds down. Thursday the 30th and Friday the 31st have surfable early sessions at 4ft and 3ft, clean, but the energy drops back to moderate levels (293-499). Good if you're keen, but not a highlight.

There's a longer gap through the first few days of August, with a drop to smaller 1ft to 2ft waves. Still, Saturday the 1st has clean 2ft waves with a long 14-second period, so you could get a few fun ones if you're not picky.

Then, for those planning ahead, look at Wednesday the 5th of August. We get another spike: a 6ft southerly swell with a very long 15-second period and clean conditions from the north-northwest. Combined energy is strong at 1212. This is another one for the experts, with excellent surf conditions forecast. A promising long-range standout, though a bit less certain this far out.

That's the story, mate. The best bet is the morning of the 28th of July and the morning of the 5th of August for the big, clean groundswell action. Everything else is just filler.

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.
