The Lowdown

Alright, let’s get to it.

The next couple of weeks are a mixed bag, to be honest. We’ve got a pulse of energy early on, but it’s messy and blown out. The real window looks like it’s around the middle of next week, with a few cleaner windows if you’re willing to wait.

Sunday morning kicks things off with a solid 8ft of NE swell, but that wind is howling at 31 mph from the NNE. It’s technically cross-off, but with that much juice, it’s going to be a washing machine. The energy is strong (1281), but it’s not worth the fight. The afternoon jumps up to 13ft from the ENE, but that’s just a mess. That’s a lot of water moving, and with that wind, it’s more of a survival mission than a surf. Not our day.

Monday morning drops to 8ft from the ENE, wind easing to 16 mph. It’s still cross-off and clean, but the energy is moderate (1517). It’s rideable, but nothing that’s going to make you skip work. The afternoon gets a bit lumpy with the cross wind picking up.

Tuesday sees the swell drop to 6ft, but the wind stays cross and the energy drops way off (515). The surf is small and the conditions are average. You’re not missing much.

Wednesday morning gives us a small 4ft SE swell with light 9 mph NNE cross-off winds. The energy reading is weak (392), but it’s clean. A glimmer of hope, but still pretty small.

Thursday is poor, with onshore winds and small, short-period swell. Forget it.

Friday morning looks a little better. Small, 4ft SE swell, light winds, clean conditions. The energy is very weak (282), but if you’re a log enthusiast, you might find something. The afternoon gets a cross-on breeze and stays small.

From Saturday through to Monday, we’re looking at a definite lull. The swell drops out to under 3ft, the period is long and slow, and it’s all cross-shore chop. That’s a stretch of a few days with nothing on offer. The only real highlight in that grey period is a possible cleaner window on the 15th.

Yes, let’s talk about Tuesday the 15th. The afternoon shows a late-day improvement. We have 5ft of E swell, light 9 mph NNE cross-off winds, and the guidance is calling for very good conditions. The energy is still moderate (586), but it’s the best combination of size and clean conditions we’ve seen. This is your best bet for a proper surf this week.

After that, it’s a slow fade. Wednesday and Thursday are back to small, weak, and onshore. You’ll be checking the forecast every hour hoping for a change. The following week, from the 18th on, is mostly small and poor, with glimmers of glassy mornings and tiny waves. Nothing worth planning a trip around.

The water temp is about average for this time of year, which is a bonus as we head into the weekend.

So, there you go. The standout is clearly Tuesday the 15th afternoon. It’s not huge, but it’s clean and rideable. Be patient until then.

Rusty.

Information about the Unnamed Surf forecast

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