The Lowdown

G’day, Rusty here. We’ve got a solid 16-day stretch ahead at Downtowns, so let’s dive in. This is a reef break, fairly consistent, and it’s going to be delivering for those who know what they’re doing—this one’s for advanced surfers only for most of the run.

There’s no gap at the start; the first swell’s already rolling in. Wednesday the 2nd kicks off with a clean 7ft SW groundswell, and the afternoon turns on with offshore ESE breeze at 6 mph. That’s glassy, lined-up, and packing proper energy—combined energy of all swells directed here sits at (2053), which is moderate to strong. Water temp is 80°, which is about average for the time of year. That afternoon session is a standout for the first week.

Thursday the 3rd morning is a bit messy with a crosswind, but the afternoon cleans up again with offshore ESE breeze and 5ft SW swell at 16 seconds—clean, long-period groundswell, perfect for the reef. Friday the 4th afternoon holds similar vibes with 5ft SW and a cross-offshore SE wind. Saturday the 5th and Sunday the 6th see the swell bumping up to 6-7ft, but the winds turn cross-shore and a little stronger, so quality drops—still surfable, but not the pick.

Monday the 7th and Tuesday the 8th have the swell building back up, with Tuesday afternoon pushing 8ft SSW and a 18-second period—that’s serious energy (4504). But the wind is cross-shore, so it’ll be a bit lumpy. Wednesday the 9th is similar, with a cross-onshore wind in the morning making it choppy. Not the best.

Now, the real standout is Sunday the 13th. The morning shows 10ft SW swell at 18 seconds—very long-period groundswell, huge energy (5299). The afternoon is what dreams are made of: clean offshore ESE breeze at 9 mph, glassy face, 10ft SW. That’s expert territory, but if you’re skilled, that’s the session of the whole forecast. It’s a solid 16-day call, but worth locking in.

Monday the 14th afternoon cleans up again with 7ft SW and offshore ESE wind—another strong session. Tuesday the 15th afternoon is similar with 6ft SW and offshore conditions. Wednesday the 16th afternoon has 8ft SSW and cross-offshore SE wind, clean and powerful. Thursday the 17th afternoon finishes the run with glassy conditions—8ft SSW and dead calm. That is a rare, beautiful way to end the stretch.

Crowds at Downtowns are sometimes an issue, so early and late sessions will be your friend.

Rusty.

Information about the Downtowns Surf forecast

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