G’day, Rusty here. We’ve got one spot on the radar for the next couple of weeks: Cobden Breakwater. The water temp is sitting at about 56°, which is average for the season, no surprises there. The outlook starts off mixed, but there are a couple of sessions that’ll get the blood pumping.

First up, Saturday morning (July 4th) – we’ve got 8ft swell from the WNW at 11 seconds. That’s a solid groundswell with serious energy (1709), but the wind is a fresh NNE breeze at 19 mph, blowing cross-offshore. It’s clean, but 8ft is a lot for this break, and the wind makes it a bit marginal. Not the pick.

Now, Sunday afternoon (July 5th) is the standout for the first week. The wind drops to glassy calm, and we’ve got a 8ft swell from the WNW at 10 seconds. Moderate energy (1554), but with zero wind, the conditions will be pristine. This is a solid intermediate-to-expert wave – 8ft is getting up there, but the clean faces will make it a ripper. If you’ve got the skills, this is the session.

Monday (July 6th) sees a big jump – 10ft in the morning from the west, with a super long period of 16 seconds. That’s very long period groundswell, and the combined energy is cranked to 4136. But the wind is a gentle cross-shore, and the comment flags marginal conditions due to tide. This is heavy, powerful stuff – only for experts, and even then, it might be a handful. The long period will make it wall up at the breakwater.

For the second week, it gets smaller but cleaner. Thursday afternoon (July 15th) is the longer-range standout. We’ve got 6ft from the west, but the period jumps to 17 seconds – that’s a very long period, and the energy is 2583. The wind is light offshore from the ENE at 6 mph, so it’ll be glassy clean. This is a proper groundswell, and at Cobden Breakwater, that long period will set up beautifully. It’s listed as excellent for experienced surfers. Mark it, but it’s a week and a half away, so keep checking.

After that, it fades. From July 17th through the 19th, we’re down to 3ft to 3ft swells from the WSW, with light to moderate winds. Clean enough for a small wave if you’re keen, but nothing special.

The best on offer is Sunday afternoon (July 5th) for a glassy 8ft wave, and that Thursday July 15th session for the long-period offshore gem. Cobden Breakwater is fairly consistent, so even the smaller days can surprise. This window has its highs and lows, but there’s fun to be had.

Stay salty,
Rusty

Information about the Cobden Breakwater Surf forecast

The above surf forecast table for Cobden Breakwater provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobden Breakwater can be found by selecting the local surf guide option on the grey menu. Our Cobden Breakwater 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 (Cobden Breakwater) 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 Cobden Breakwater 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.

Cobden Breakwater is 172 km (107 miles) from the city of Christchurch. If you plan a holiday in West Coast South Island, look for hotels and other accommodation in Christchurch. Christchurch has rooms for a wide range of budgets as well as car hire and transport links.
