The Lowdown

G’day, Rusty here. Let’s cut to the chase. The next couple weeks are a rollercoaster, with one clear winner early on and then a long, bumpy stretch of onshore junk. The standout is that Friday morning, and the rest is about picking your moments, or just giving it a miss.

The first real surf is on the morning of Friday the 7th, and the water’s about 55°F, which is pretty normal for this time of year—nothing out of the ordinary.

That Friday morning is the pick of the whole run. Dee Dees (Big Island) will have a solid 6ft of south swell, with a long 15-second period. The wind is a light 9 mph cross-offshore, keeping it clean. The energy is strong, with a combined reading of 1546. It’s a fairly consistent reef break, and the swell direction is spot on. This is your session—clean, powerful, and with a “sometimes” crowd, you’ve got a shot at some empty ones. This is the one to move your schedule for.

Friday afternoon gets lumpy with a fresh 19 mph cross-shore, and it’s all downhill from there. The weekend is marginal—Saturday morning has light winds but small, short-period swell. Sunday is clean but tiny, only 3ft, not worth the paddle.

Then comes a big dead spell. From Monday the 10th through Thursday the 14th, it’s flat to tiny, with poor conditions and almost no energy. There’s a glassy moment on Friday morning the 14th, but the swell is only 0.7ft—completely flat. That’s a four-day stretch where the surfboard stays in the car.

Things pick up on Saturday the 15th and Sunday the 16th, but it’s bad news. The swell builds to 6ft and 7ft, but the wind is a fresh 19 mph cross-onshore, making it a lumpy, choppy mess. That’s a write-off, no two ways about it.

The big one hits on Tuesday the 18th, with the swell jumping to 12ft from the south, and a 13-second period. That’s a powerful, strong-energy system (3916). But the wind is still howling at 19 mph cross-onshore. It’s going to be a giant, closed-out mess—this is kite territory, not paddle surfing. Even with the wind easing to 16 mph later, it’s still rough and heavy. Only experts need even look, and even then, it’s not inviting.

Looking further out, Wednesday the 19th sees the swell drop to 7ft with lighter winds, but it’s still marginal. Thursday morning the 20th looks cleaner with a light cross-offshore, but the swell fades to 3ft. It’s a long way out, so less certain, but the trend isn't good.

So, here’s the plan: get out there Friday morning the 7th. That’s your window, don’t sleep on it. After that, it’s a rough ride, and that big swell on the 18th is a bust with the wind. The ocean will come around again; it always does.

Rusty.

Information about the Dee Dees Surf forecast

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

Dee Dees is 40 km (25 miles) from Lower Hutt. If you plan a holiday in The Wairarapa, look for hotels and other accommodation in Lower Hutt. Lower Hutt has rooms for a wide range of budgets as well as car hire and transport links.
