The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe at Dee Dees over the next couple of weeks. It’s a bit of a mixed bag, with some definite highlights and some real duds.
First up, the water temp is sitting at about 55°, which is just a touch warmer than normal for this time of year – nothing wild, but a little pleasant surprise.
The week starts off with a couple of clean but small options. Tuesday morning the 15th is probably your best early bet. We’ve got a clean 4 ft S swell rolling in with a 10-second period and a light offshore breeze from the north. It’s not huge, but conditions will be good. The combined energy is moderate at 321, so there’s enough there to have fun on a shortboard. The vibe will be clean. That afternoon gets super glassy with a tiny 2 ft SSW swell, but it’s just not got much push.
Then things go pretty quiet, and I mean *quiet*. From Wednesday the 16th through Friday the 18th, it’s mostly blown out or just too small. Wednesday gets absolutely hammered by 28 mph winds, making a mess of the 1 ft leftovers. There’s a brief moment Friday morning with no wind and a 3 ft swell, but the period is a short 6 seconds, so it's pretty weak.
Now, the real standout. Saturday the 19th morning is where it’s at. We’ve got a clean 3 ft S swell, but the energy is ramping up nicely to 436 – that’s moderate but solid – and the period stretches to a nice 14 seconds. That’s proper groundswell, giving you some real push. The wind is a light cross-offshore from the north, so Dee Dees should be holding shape beautifully. Surf's clean, conditions are good. This is your best session of the run. Don’t sleep on it. The afternoon gets chewed up by a 22 mph cross-shore.
Heads up for the 20th and 21st. We get a big pulse of SSW swell, hitting 8 ft to 8 ft. That’s a big wave. The wind and tide are favorable, but this thing is going to be too big for Dee Dees – it’s a reef break, but that much water moving around is for experts only. Combined energy is through the roof, 1163 on Sunday the 20th afternoon and 1225 on Monday morning. If you’re a solid charger, maybe, but the comment says it’s too big for the break, so be smart.
After that, from the 22nd through the end of the month, it’s a long, drawn-out run of average to poor conditions. Lots of cross-onshore winds and messy chop. The 23rd and 24th see another big, lumpy SSW swell (12 ft!) with strong winds – that’s more of a kite-surfing setup than a paddle session. There’s a small, clean blip on the morning of the 26th, with a 2 ft SSW swell and an offshore easterly, but it’s very small.
The very last days of September and into the 29th are mostly tiny, weak, and cross-shore, apart from the 29th afternoon which goes glassy but with only 2 ft of swell.
So there you have it. The pick of the litter is Saturday morning the 19th. Go get it.

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.
