The Lowdown
G’day, I’m Rusty. Let’s talk about what’s on the cards for Dee Dees over the next couple of weeks.
Right off the bat, it’s a quiet start. The first few days are pretty grim – tiny swell and messy conditions. Thursday the 13th and Friday the 14th are basically flat, with waves barely 0.7ft to 1.0ft and poor surf. The combined energy is weak, sitting between 35 and 51, so don’t bother paddling out. Saturday morning the 15th cleans up briefly with glassy conditions and a 1.0ft SSE swell, but it’s only a 1/10 score – just not enough oomph.
Then it gets wild. Sunday the 16th sees a jump to 12ft SSW swell, but the period is a short 8 seconds and the wind is howling from the south at 40 km/h, creating a nasty cross-shore chop. The energy spikes to 1786, but it’s a mess – only for the brave and the experienced. Monday the 17th stays big and choppy, then Tuesday the 18th is more of the same with 10ft and 8ft swells, all cross-onshore.
Now, here’s the standout. Wednesday the 19th is a big one – a massive 13ft swell from the south, with a long 16-second period (groundswell), pushing the combined energy to 7940 in the morning. The wind is moderate cross-onshore, but the forecast says wind and tide are favorable. However, the swell is too big for this reef break – it’s a warning, not an invitation. Only experts should even think about it, and even then, it’s risky. The afternoon stays big at 12ft with onshore wind.
Things calm down after that. Thursday the 20th morning is the pick of the second week: 7ft S swell, 12-second period, glassy conditions, and light winds from the WSW. The energy is 1134, and the guidance says excellent for experienced surfers. This is your best window – clean, punchy, and with Dee Dees being a fairly consistent reef, it’ll hold shape. The optimum swell direction is S, and that’s exactly what’s coming. Crowds are sometimes an issue here, so it might be worth an early paddle.
Friday the 21st drops to 5ft, still from the south, but the conditions are marginal. The weekend of the 22nd and 23rd sees small 3ft to 4ft S swells with clean mornings, but the energy is low (355 to 401), so it’s more of a longboard session. After that, the wind picks up again, and by the 27th and 28th, it’s back to tiny, choppy slop.
Water temperature is about average for the time of year – nothing unusual there.
Overall, Wednesday the 19th is the big, dangerous standout, and Thursday the 20th morning is your best bet for a solid, clean session. Don’t get too excited about the second week – it fades out.
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.
