The Lowdown
Alright, folks, Rusty here with a look at what’s to come at Doran Beach.
Right off the bat, it’s a bit of a slow start, but there are some windows. The water temp is sitting around 60°, which is about normal for this time of year.
The first real chance to get wet isn’t until Thursday morning, September 17th. We’ve got a tiny 2ft groundswell from the SSW with a very long 16-second period. The wind is glassy, making for a clean surface. It’s not going to be big, but for the beach break setup here, that long period stuff can straighten out, so watch for that. The combined wave energy is moderate (374).
Friday, September 18th, sees similar tiny 2ft swell from the SW with a very long 19-second period. The wind is light and cross-shore, so not perfect.
Saturday afternoon, September 19th, a fresh pulse of 7ft swell from the WNW shows up, but with a short 6-second period and a moderate breeze. It’ll be a bit disorganized.
Sunday, September 20th, is a bit of a mixed bag. The morning offers a tiny 2ft SSW groundswell with an 18-second period and clean conditions from a light offshore wind. The energy is moderate (535). It’s the best wave quality of the early period for a clean, small-wave session. That afternoon, a 7ft WNW swell (7-second period) kicks up again, but the period is short.
The following Monday (September 21st) and Tuesday (September 22nd) look average with 5ft to 6ft swells. Tuesday afternoon the wind turns light offshore and clean, with a 5ft NW groundswell at 10 seconds. That looks like a fun, clean option (combined energy 692).
The highlight, the one to keep an eye on, comes at the very end of the forecast. On Tuesday morning, September 29th, we’re looking at a solid 7ft groundswell from the WNW with a 10-second period and light offshore winds. The combined energy is strong (1321). That afternoon it gets bigger with a 10ft swell (8-second period) and a stiff offshore wind. That’s big for Doran – for experts only, and honestly, at 10ft, it might be too big for this break and more interesting for the kite crew. The Tuesday morning session looks like the true standout of the whole 16 days.
There's a solid run of small, clean surf in the second week around the 24th and 25th, but nothing that jumps out as epic. The period between the 17th and the 29th has a few flat spells, but it’s not a dead run for too long.
Rusty.

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