The Lowdown

G’day, it’s Rusty here. Let’s cut through the noise and get straight to it. The next couple weeks are a mixed bag, with just a few windows that’ll get the heart pumping. The first standout comes Saturday the 22nd, and then we’ve got another promising run right at the end there, around Wednesday the 26th. But between now and then, you’ll have to pick your moments carefully—there’s plenty of wind and swell to sort through.

Kicking things off at Dee-Dees (Big Island) this coming Saturday morning, the 15th, we’ve got tiny 1 ft surf with a 17-second period rolling in from the SSW. Water temp’s at 54°, which is about normal for this time of year. The light ENE breeze is holding it clean, but honestly, it’s pretty marginal—you might catch a slow, mushy one if you’re desperate. The afternoon is a touch better with 1 ft and glassy conditions, but it’s still very ordinary, not worth rushing out for.

Sunday the 16th, a big pulse moves in—15 ft from the SSW, but it’s coming with a strong south wind at 25 mph, making it a complete mess. Cross-onshore, lumpy, and just not surfable. Same story carries into Monday morning; the swell’s still solid at 8 ft, but the south wind’s still cross, so it’s going to be too big and messy for this break. Monday afternoon eases to 3 ft with a longer 14-second period, but still cross-shore and chopped up, only a marginal call.

Tuesday the 18th is more of the same—strong winds from the SSW, cross-onshore, and surf size jumping around between 8 ft and 15 ft. Not your day. Wednesday keeps that pattern alive, with 12 ft to 15 ft and relentless cross-onshore conditions, just poor quality all around.

Now, Thursday the 20th is worth a mention, even though it’s still too big for Dee-Dees. Onshore winds pick up a bit of an angle, and the swell drops to 7 ft–8 ft, but the forecast is pretty clear: it’s still too much for this spot. The afternoon turns glassy, which is nice, but the wave’s just oversize. Not ideal.

Then, finally, a window opens. Friday morning, the 21st, the wind shifts to a light NNE cross-off, and the swell drops to a clean 6 ft from the south with a long 16-second period. Conditions look excellent for experienced surfers—clean lines, proper push. That’s the best of the first week. The afternoon fades a bit with a cross-shore breeze, but the morning is the one to hit.

Saturday the 22nd morning keeps things rolling—4 ft from the SSW with an offshore N wind, clean and glassy. It’s a good, fun day, but the crowd factor could be a thing as it’s a fairly consistent spot. Saturday afternoon, however, the wind swings to the NW at 25 mph, turning it messy again. Sunday the 23rd is mostly a write-off with strong crosswinds and weak, mixed-up waves.

After that, there’s a lull—Monday the 24th brings tiny, short-period stuff from the NW, nothing special. But then, look out for Wednesday the 26th. Morning starts with 7 ft from the NW, but that’s still tipped to be too big for this break. The afternoon is the real gem: the wind goes calm, and you’ve got 3 ft of SSW swell with a 15-second period, clean and glassy. Small but beautiful, and perfect for a longboard or a funboard.

The last few days of the forecast, from Thursday the 27th through the 30th, are pretty forgettable—weak swells, some onshore winds, and generally small, choppy stuff. Not worth planning around.

So, bottom line: the standout is Friday the 21st morning with clean, solid 6 ft surf from the south. Saturday the 22nd morning is a solid second pick, and Wednesday the 26th afternoon has that glassy, long-period magic, just smaller. Keep an eye on the winds—they’ll make or break these windows.

Stay stoked,

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.
