The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on the cards for Dee Dees.
We’ve got a solid run of surf kicking off this Friday, July 17th, and it’s looking pretty good to start. The swell is running at a clean 4.6 ft from the SSW with a period of 14 seconds – that’s a proper groundswell with some real energy behind it, registering a strong 1082 combined energy. The wind is a light offshore from the NE, keeping things tidy. The water temp is sitting at 55.2°, which is about 1.4° above normal, so nothing too wild there, just a touch warmer than average for this time of year. Friday morning is the standout for the experienced surfers, with excellent conditions. The wave quality will be good, but that 4.6 ft swell with a longer period might make it break a bit straight at a beach break, so keep that in mind, but here at Dee Dees (a reef), it should handle it nicely.
Friday afternoon, the wind goes glassy from the E, and the swell holds at 4.6 ft from the SSW with a 15-second period – that’s a very long period groundswell, which means real power and shape. The combined energy is still a strong 942. Expect very good, clean surf. Crowds are sometimes a thing here, so you might have some company, but it’s worth it.
Saturday the 18th gets bigger. The morning is a bit cross with a NNW breeze at 6 mph, and the swell is 4.3 ft from the SSW (14 seconds, 1237 energy). It’s marginal. The real story is Saturday afternoon: a massive jump to 6.9 ft from the SSW with a 22-second period – that’s an absurdly long period groundswell, and the combined energy is a whopping 4197. The wind is onshore from the W at 6 mph, though. This is a wave for experts only. At over 8.2 ft, it’s too big for most, and the period is so long it could be tricky at beach breaks, but here at the reef, it might hold some special lines. The forecast says it’s too big for this break, so be careful.
Sunday the 19th is a beauty. The morning is glassy with a SW wind at 3 mph, and the swell is 6.2 ft from the SSW (16 seconds, 1909 energy). That’s excellent, clean surf for experienced surfers. The afternoon stays clean with a cross-off SE breeze and 5.9 ft swell (16 seconds, 1563 energy). This is a top call for the weekend.
Monday the 20th keeps the run going. The morning has an offshore E wind, 5.9 ft from the SSW (14 seconds, 2201 energy). Clean surf. The afternoon, however, gets a bomb: 9.8 ft from the SSW with a 19-second period, a massive 5316 energy. That’s for experts only, and the reports say it’s too big for this break. The wind is offshore, so it’ll be clean, but it’s a monster.
Tuesday the 21st is still solid in the morning – 6.6 ft from the S (14 seconds, 1543 energy) with a cross-off NNE breeze. Clean and excellent. The afternoon gets messy with a cross-shore NNW wind and the swell dropping to 5.6 ft, so that’s a pass.
From Wednesday the 22nd, the swell starts to fade. The 22nd has a weak 3.9 ft from the SSW (12 seconds, 427 energy) with onshore wind in the morning – marginal. The afternoon improves to 3.6 ft with a cross-off breeze, but it’s just average.
Thursday the 23rd is ordinary. The swell is down to 2.6 ft with a short 8-second period, making for weak, uninteresting waves. The wind is cross-off in the morning but cross in the afternoon. Not worth it.
Friday the 24th has a small 2.3 ft S swell in the morning with a cross-on breeze – poor. The afternoon gets interesting though: a sudden 8.2 ft from the SSW with a short 7-second period (545 energy). The wind goes glassy from the SW, so it’ll be clean, but that’s a big, short-period swell that’s too big for this break and likely messy. Experts only if you’re keen.
Saturday the 25th is a write-off. Strong SSW winds at 25 mph, messy cross-on conditions, and a 5.6 ft to 3.9 ft swell. Poor surf. This is more of a kite-surfing setup than a paddle situation.
Sunday the 26th offers a bit of a comeback. The morning has a 5.2 ft S swell (8 seconds, 642 energy) with a cross-off N breeze, making for very good, clean waves.

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.
