The Lowdown

Alright, let’s get into it. The long-range charts are showing a proper pulse of west-northwest energy heading our way, but this swell window is a bit of a mixed bag. We’ve got a slow start, then a big, powerful, and potentially unruly middle section, and then a cleaner, juicier finish. It’s not going to be a non-stop party, but there are definitely some windows where Dumps will be the place to be.

The first real call is Wednesday the 5th. It’s not going to be pretty. We’re looking at a solid 7ft of southwest swell pushing through, but a 25 km/h north-northwest cross-on breeze is going to chop it right up. The energy is already showing strong (2390), but the surface is going to be a mess. Not worth suiting up for unless you’re desperate for a paddle.

Thursday the 6th is where things get interesting. The swell jumps to 12ft, and while the period drops a bit to 13 seconds, the wind swings around to the southeast and becomes a light cross-off. That’s a big improvement for quality. The energy is pumping (3672), but at this size, Dumps is going to be a handful. This is for experienced surfers only. It’s clean, but it’s powerful and relentless.

Friday the 7th is the standout of this first week. We’ve got a solid 10ft of southwest swell, a 14-second period, and a light southeast offshore breeze in the morning. The energy is strong (4062), and the conditions are described as excellent for experienced surfers. This is the day to be out there if you can handle it. The afternoon sees the swell bump up to 12ft with a bit of a cross-shore ripple, but the morning is the clear winner.

The weekend is a step down. Saturday the 8th starts with a cleaner 8ft of southwest swell and a light offshore wind. It’s still solid, but the energy drops off (2376). It’s still a good option for the more experienced crew. Sunday the 9th is a write-off. The swell is big (12ft) but the wind is howling at 45 km/h from the southeast. By the afternoon it jumps to 15ft with a massive energy reading (7830), but it’s going to be a washing machine. Not worth it.

After that, we get a bit of a lull. Monday the 10th and Tuesday the 11th are small and weak. The swell drops to 5ft and the energy is low (638). Not much happening. Tuesday afternoon does look clean with a light offshore wind, but it’s small.

The second week starts to show some promise. Wednesday the 12th has a nice pulse of long-period southwest swell (18 seconds) at 5ft. That’s a classic groundswell, and with light offshore winds, it should be clean and lined up. The energy is moderate (1464). This is a good call for a wider range of surfers.

Thursday the 13th looks like the pick of the second week. The swell is 7ft from the west-southwest with a 15-second period. The wind is glassy in the morning. The energy is pushing 1739, and the surf is described as excellent for experienced surfers. It’s a great day, but you’ll want to be comfortable on a bigger board.

The rest of the week is small and clean but not particularly exciting. Friday the 14th has some glassy 5ft leftovers. The weekend sees a bit of an onshore breeze and the swell fades. By the 17th, we’re looking at a short-period, wind-blown mess.

But then, the finale. The 18th and 19th see another big swell arrive. The 18th has 12ft of west-southwest swell with a strong, clean cross-off wind. The energy is pumping (3407). It’s going to be big and powerful, but clean. And then the 20th looks absolutely massive. The swell is forecast at 18ft with a 14-second period. The energy reading is off the charts at 12310. This is a serious, XXL event. Only the most experienced chargers should even think about it. It’s a long-range call, so don’t book the time off yet, but if it comes together, it could be the swell of the month.

So, to sum it up: this period starts slow, gets big and gnarly in the middle, then cleans up for a solid run in the second week, and ends with a monster. The real standouts are Friday the 7th and Thursday the 13th. The 20th is a wildcard of epic proportions, but it’s a long way out.

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.
