The Lowdown

Alright, Rusty here. Let’s have a look at what we’ve got cookin’ over this 16-day stretch.

First up, the water at Dumps is runnin’ cold. We’re talkin’ 56.3°F and that’s a solid 3.6°F cooler than what’s usual for this time of year. Bit of a shock to the system when you first get in, but you’ll adjust.

Right off the bat, Sunday the 2nd gets things started. It’s not a world-beater, but the morning is showing a clean 4.3ft swell out of the WSW with a nice 13-second period. The wind is light and variable so it’s lookin’ glassy. That’s a good sign for an afternoon paddle if the wind holds.

Monday the 3rd is where it starts to feel a little more real. Morning has 4.6ft of SW groundswell with 13 seconds, glassy conditions again, and the wave energy is up there at 865 (moderate). The afternoon cleans up with a cross-off breeze. That’s solid fun for a summer weekday.

Tuesday the 4th stays tidy in the morning – 4.6ft, SW, clean cross-off winds. It’s not pumping, but it’s very surfable. The afternoon gets a bit onshore and sloppy though, so get your waves early.

Now, Wednesday the 5th sees the swell kick up, but the wind turns against us. Morning has a 6.6ft SW swell, but the wind is cross-on from the NNW at just over 9 mph, and the period jumps to a very long 16 seconds. That combination is messy – choppy and hard to line up. Wave energy is strong at 2005. The afternoon gets a bit bigger at 8.2ft with a 15-second period, but wind stays onshore. This is more of a washout than a winner.

Thursday the 6th is the first real standout for me. Morning brings a solid 9.8ft of SW groundswell, light offshore wind from the SE, and the energy is thumping at 3253 (strong). The period is 13 seconds. That’s a proper clean groundswell stacking in. This is for experienced surfers only though – 9.8ft is big. The afternoon stays clean with the swell dropping slightly to 8.2ft. If you’ve got the skill and the cojones, Thursday is your day.

Friday the 7th sees the swell holding at 9.8ft with a 14-second period, but the wind is not cooperating. It’s cross-on in the morning and onshore in the afternoon. The raw power is there, but the surface is gonna be bumpy. A bit frustrating with that much energy in the water.

Saturday the 8th – forget it. The swell jumps to a ludicrous 23.0ft in the morning with a 14-second period. The combined energy is 19561 (very strong). This is massive, dangerous, and with a moderate onshore wind, it’s just a washing machine. The afternoon is 24.6ft and 15 seconds, energy at 23304. Even the file says it’s too big for this break. That’s a hard pass.

Sunday the 9th is still way too big for a paddle. 14.8ft in the morning with 15 seconds, even if it’s glassy. The afternoon drops to 11.5ft. These are expert-only, and even then, the break might not handle it well. Keep your feet dry.

Monday the 10th brings a nice reset. The swell drops to a friendly 5.2ft in the morning, and it’s glassy. The period is a shorter 10 seconds, so less grunt, but good for a cruisy session. Wave energy is back to moderate levels (562).

Tuesday the 11th is clean in the morning with a 4.9ft SW swell and offshore ESE wind at around 6 mph. That’s a nice, clean, manageable wave. The afternoon has an interesting little pulse – a tiny 3.0ft swell but with a very long 18-second period. That’s a lot of waiting, but when it comes, it’ll have some push. Better

Information about the Dumps Surf forecast

The above surf forecast table for Dumps provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dumps can be found by selecting the local surf guide option on the grey menu. Our Dumps 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 (Dumps) 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 Dumps 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.
