The Lowdown
Alright, let's break this down. The first thing that jumps out is Dee Dees. This reef break is exposed to the swell, and it wants an S direction, which is exactly what we're getting for the opening window. The water temp is about average for this time of year, so no drama there.
We kick off on Thursday, August 27th. Not a bad start. The morning is cloudy with a gentle offshore breeze from the east at 9 mph, and we've got a solid 6ft SSW groundswell churning in with a period of 17 seconds. That's proper long-period energy, and the combined energy is a massive 2171 (very strong wave energy). This is excellent surf, but it's a reef break, so it's for experienced surfers only. The afternoon holds up too, with a 7ft S swell at 16 seconds, still clean with a moderate offshore wind. The combined energy is 2247 (very strong wave energy). This is the standout of the entire forecast—two sessions of proper, clean, powerful surf.
Friday, the 28th, is a letdown. The morning swell drops to 4ft, and the wind swings to a cross-offshore from the north at 19 mph, which messes up the face. The period is still decent at 12 seconds, but the energy is a moderate 577. The afternoon is a write-off with strong cross-shore winds and poor conditions.
The whole weekend is a no-go. Saturday and Sunday are dominated by NNW winds with cross-shore and cross-on conditions, and the swell is tiny and weak. The combined energy stays below 500 (weak to moderate). Nothing to paddle out for.
Now, here's a tease. Monday, August 31st, and Tuesday, September 1st, see a massive jump in swell. We're looking at 10ft SSW groundswells with a 12-second period, and the combined energy hits 2364 and 2429 (very strong wave energy). The wind is light and offshore, so it would be clean. But the problem is the size. Over 8ft on a reef is expert territory, and the forecast itself says it's too big for this break. This is a big wave day for the brave or the dumb, not a recommendation for a normal surfer.
After that, the outlook gets grim. From Wednesday, September 2nd, all the way through to Friday, September 11th, it's a constant stream of strong NW winds, cross-shore and cross-on conditions, and messy, blown-out surf. The swell is all over the place, with periods dropping below 8 seconds at times, and the combined energy rarely breaks 1000. There's a brief moment on Monday afternoon, September 7th, where the wind goes glassy and the swell is 1ft, but the energy is a pathetic 94 (weak). It's surfable but extremely ordinary.
Overall, the entire 16-day window has a massive gap of poor conditions from the 28th of August right through to the 11th of September. Your only real window is the first day, Thursday the 27th. That's the one to circle. After that, you're better off doing something else.

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.
