The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the cards for the next couple of weeks.
To be honest, it’s a pretty quiet run for the most part. We’ve got a solid window of very small, marginal surf stretching from Thursday the 23rd of July all the way through until the end of the month. The water temp is sitting at 74°, which is a whopping 7° warmer than usual for this time of year – that’s a real standout, feels like bath water out there.
The first real flicker of something worth a look comes on Monday the 27th of July at Trestles (Lowers). The morning will see a 4ft swell from the SSW, with a nice long 18-second period. That’s proper groundswell energy, and it’s packing moderate energy (1106). The wind is light out of the SSW, which is actually onshore, but it’s a light breeze, so it won’t be too messy. The afternoon cleans up a bit more with the wind swinging to the SW and staying light. The swell drops a touch to 4ft, but it’s still got that long period grunt. This is a surf for the experienced crew – the wave size is manageable for them, but the long period will make it a bit more challenging at a beach and reef setup, so keep your wits about you. The crowds here are always thick, so expect a full lineup.
The real standout, the one that’s got my heart pumping a bit, is Tuesday the 28th of July. The morning shows a 5ft swell from the SSW, period of 17 seconds, and the combined energy is strong (1156). The wind is light and onshore from the SW, but the swell quality is the best of the whole run. This is the pick of the period. The afternoon holds similar size and energy (1124). It’s still only good for the intermediate to advanced surfer, but if you’re on it, get out there.
After that, we see a slow fade. Wednesday the 29th of July is still rideable with 4ft to 4ft and 16-second period, but the energy is dropping off (797). Thursday the 30th of July is a write-off with poor conditions and a 4ft swell but bumpy 12 mph wind. The first week of August is a real letdown. From Saturday the 1st of August, we get a pulse of 6ft swell from the S, but the period drops to 13 seconds, and the energy is moderate (1307). The wind is light and onshore, and the size is pushing into the “too big for beginners” zone. It’s marginal, not great.
Then from Sunday the 2nd of August through to Friday the 7th of August, it’s just small, poor quality dribble. We’re talking 1ft to 3ft, with short periods and onshore winds. The combined energy is weak, often under 200. It’s a proper blank stretch. Don’t bother. The swell is too weak and the wind is mostly cross-onshore, making it a choppy mess. For a few days there, at a beach and reef setup like Trestles, it’s more interesting for kite surfing than paddle surfing.
So the bottom line: get your best sessions in on Monday the 27th and Tuesday the 28th of July. The rest of the run is a waiting game.
Rusty.
