The Lowdown

Alright, let’s talk about the next couple of weeks. For the first few days, you can leave the boards in the car. There’s a lot of wind and messy surf on the way before things clean up.

Your first good window is Sunday the 13th. The morning is looking clean with a light offshore breeze. We’ve got a long-period NW groundswell pushing in around `3ft` at `13s` and the energy is moderate at `344`. It won’t be big, but it’ll have some push and shape. Sea temp is about normal for this time of year. A classic, clean way to start the day.

Monday the 14th is another early morning call. It’s dead glassy with a `3ft` NW swell at `11s`. The energy is moderate (`283`). It’ll be small but clean, perfect for getting a few long rides without too much drama. The wind is calm, which is a major positive.

Then it gets a bit wild. From Tuesday the 15th through Friday the 18th, the onshores stomp in and the ocean gets messy. The swell builds, but it comes with a lot of north wind. Sizes push up over `7ft` and even hit `12ft` on Wednesday the 16th, but it’s blown out, cross-onshore, and rough. The energy is strong to very strong, but it’s not doing anyone any favors for paddling. Honestly, this setup looks more interesting for kite surfing than for paddle surfing.

We get a little break Saturday morning the 19th. There’s a `4ft` NW swell with a `14s` period and only a light cross-shore wind. The energy is strong at `942`, but the comment is marginal. It’s a long-period swell, so it might be a bit straight at a beach break, but worth a look if you’re keen.

Now, here’s the standout. Monday the 21st is your best bet. The morning is glassy, with a `4ft` NW swell running at a long `16s`. The energy is very strong at `1084`. This is the good stuff. It's clean, it's got power, and the conditions are lined up for experienced surfers. This is the one to circle on the calendar.

The rest of that week stays rideable. Tuesday morning the 22nd has `6ft` of NW swell at `13s`, but the wind is onshore. Wednesday morning the 23rd and Thursday morning the 24th both have glassy conditions, but the swell drops off and the energy weakens.

After that, the surf fades out. The last week of the period sees the swell shrink and the onshores return, leaving us with small and wind-blown conditions. Nothing worth getting excited about from Friday the 25th all the way to the end of the outlook.

So, to wrap it up: your best windows are the mornings of Sunday the 13th, Monday the 14th, and that standout glassy morning on Monday the 21st. Everything else in the first week is a write-off, and the second week is a slow fade. Keep your eyes on that Monday the 21st session.

Rusty.

Information about the Adraga Surf forecast

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