The Lowdown

Alright folks, Rusty here. Let's talk about what's on the cards for Doran Beach. We've got a bit of a slow burner over this 16-day stretch, so don't expect to jump straight into anything firing right now. The first few days are looking pretty average to be honest, with the first real glimmers of hope showing up around Thursday afternoon and into Friday morning. There’s a dry spell toward the end of the first week and into the second with no real standouts, then a possible flurry of activity in the middle of the second week.

Let’s get into the details. The first whisper of something decent comes on Thursday, September 3rd in the afternoon. We’ve got a WNW swell pushing 5 ft, and with a clean, cross-off wind from the WNW at 6 mph, it should tidy up nicely. The combined swell energy is moderate (617), but the period is only 10 seconds, so it’s not a classic groundswell.

Friday, September 4th morning is where the best of the early action sits. It’s glassy – actually glassy – with a 3 mph glass-off wind from the west, which is a huge plus. The swell is a clean 3 ft from the SW with a very long period of 18 seconds. That’s groundswell energy right there, with combined energy at 995, so it’s moderate but powerful for its size. Long period SW swells at a beach break like Doran can sometimes run a bit straight, but if it finds a sandbar, it’ll be the best shape of the week. The water temp is sitting at 57°, about average for this time of year, so you won’t need a steamer but a good 4/3 won't hurt.

Moving on to Monday, September 7th, both morning and afternoon look tidy. Morning is glassy again with a 3 mph SSW wind and a 4 ft S swell (14 seconds period). The afternoon picks up a bit with a 4 ft SSW swell and a clean 9 mph cross-off breeze. Consistent energy in the moderate range (694-800).

Now, a big *caveat* on Thursday, September 10th afternoon. The data shows an 12 ft S swell with 11-second period and combined energy screaming at 3160. That is huge, powerful, and way over the 8 ft expert threshold. It’s a straight up “too big for this break” situation, and with a cross-on wind, this is not for paddle surfing; it’s a kite-surfing-only show if anything.

The real standout, and the one to circle on your calendar, is Tuesday, September 15th morning. We get a 5 ft NW swell with an 8-second period. Now, the period is short, but the combined swell energy is strong (801). The wind is a light 6 mph WNW cross-off, making for clean conditions. This is the biggest clean swell of the whole run that’s actually paddleable, but at 5 ft, it's pushing the limit for beginners. The crowd profile for Doran Beach says *sometimes*, so there’s a chance of company, but with the conditions aligning, it could be a real session.

The following Wednesday, September 16th afternoon also looks promising with a 5 ft NW swell, 11-second period, a gentle 9 mph cross-off breeze, and combined energy of 643. That’s a solid, long-period option to wrap up the window.

So, to sum it up: Friday, September 4th morning is your early-bird special for glassy, long-period waves, and Tuesday, September 15th morning is the biggest clean swell of the whole outlook. The rest is mostly marginal or just too big. Forecasts can change though, so keep an eye on it.

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.
