Table - best surf conditions forecast for Dee Dees over the next 16 days.
Alright, let’s get into it. Dee Dees is a reef break, and it’s the only spot we’ve got to look at. Honestly, the first week is a real write-off. The wind is howling from the northwest, onshore or cross-shore, and it’s making a mess of things. The swell is short-period windslop, and the combined energy is weak to moderate – we’re seeing values like 256 (weak energy), 221, 215, and 122 (weak energy). The water temp is sitting at 55°F, which is bang on average for the time of year, so no surprises there.
We get a bit of a pulse on the morning of Friday, July 17th. A solid SSW groundswell comes in at 7ft, 14-second period, but the combined energy skyrockets to 1842. That’s strong wave energy. The problem is, the wind is a light cross-onshore, and the notes say it’s too big for this break. At 8ft in the afternoon, that’s strictly for the experts only. The same thing happens on Saturday, July 20th – 8ft, 14-second period, 2227 combined energy, clean wind, but again, too big for Dee Dees. That’s a real shame.
The standout moment comes on Tuesday, July 21st. The morning sees a 5ft S swell, 13-second period, with a light cross-offshore breeze and clean conditions. Combined energy is 837 (moderate energy). The afternoon cleans up even more: 5ft, 12-second period, from the S, with a light offshore from the ENE. The waves will be clean, well-shaped, and with that longer period, there will be proper gaps between sets. This is the best on offer – a proper surf window.
Later on, Friday, July 24th afternoon looks promising too. 5ft S swell, 13-second period, combined energy 977 (moderate energy), and an offshore breeze. Clean conditions. Saturday, July 25th afternoon has 6ft S swell, short 6-second period, but glassy calm wind. Combined energy is 350 (moderate energy). It’ll be a bit lumpy and less powerful, but fun for a cruiser session.
The rest of the second week is small, weak, and ordinary. Swells drop to under 3ft, combined energy dips as low as 89 (weak energy), and the wind is all over the place. Nothing to get excited about.
So, for the best surf, you’re looking at Tuesday, July 21st. That’s the day. Friday, July 24th afternoon is a solid backup. The big stuff on the 17th and 20th is just too much for this reef.

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.
