The Lowdown
Gutted, mate. Plain and simple: there is absolutely nothing rideable on the cards for the next two and a half weeks. The surf forecast is a total write-off, a flat spell that’s going to have us all staring at the horizon wondering where the ocean went.
Right from the start, Saturday the 8th is a complete dud. Tiny 2ft wind slop from the ENE with a short, weak 7-second period and a cross-onshore breeze making it choppy. The energy is pitiful, barely registering at 56. This sets the tone for what’s to come.
The entire first week is a dead loss. Day after day, morning and afternoon, we're looking at ankle-biters. Sunday and Monday keep the same miserable story: waves under 2ft, periods under 8 seconds, and that relentless ESE breeze keeping things messy. It’s the kind of surf you’d paddle out for just to float around, not to catch a wave. The energy readings are in the single digits and teens – that's not even a ripple, that’s a lake.
Things don’t improve at all as the second week rolls in. From Tuesday the 11th all the way through to Wednesday the 19th, it's a relentless run of flatness. We're talking 0.3ft to 1ft dribble with short periods. The only change is the wind direction, but it barely matters when there’s nothing to push. On the 15th, there's a slight tease of a cross-offshore breeze in the afternoon, but with 2ft of slop, it’s pointless. It’s not even worth the walk down the rocks.
Finally, on Thursday the 20th, there’s a glimpse of life. The morning shows a modest bump of energy, hitting 108, with a cross-offshore wind making the water look clean. The swell is still only 2ft from the E with an 11-second period, which is better – it has some shape – but it’s just not enough. It's the only period in the whole 16-day stretch that the models even call "surfable," and that’s a generous description. This is the best we get, and it's still a knee-high dribble. The window for beginners will be non-existent, and even for the most skilled among us on a longboard, it's marginal.
That little puff of life on the 20th fades by the 21st, and the forecast slides right back into flatness for the final few days. The energy drops back to the 20s and teens. A clean offshore breeze on the 22nd and 23rd is a cruel joke because there’s still nothing to groom.
Look, the jetty here is fairly consistent, so a blank run like this is frustrating. The good news is, it tends not to stay this poor for long. Forecasts can change in a heartbeat on this coast. For now, the boards stay in the racks, the wetsuits stay dry, and we wait. When it does come back, and it will, the water’s a warm 85°, which is dead on average for this time of year, so at least there’s that to look forward to.
Keep the faith.
