Alright, let's break down what we've got for the next couple of weeks.
The only break in the picture is Devonport Rivermouth. It's an inconsistent point and river setup, so it needs everything to line up, and honestly, most of this run looks pretty average. Water temp is around 56°F, which is about normal for this time of year.
We start off with a real dud. Friday the 10th has a tiny 1ft NW swell with a super long 16-second period, and while it's glassy, it's just too small. Saturday the 11th and Sunday the 12th see a bit more size, with a 5ft to 8ft NW swell, but the wind is howling onshore or cross-off, making it a mess. The energy is picking up through the weekend, but it's no good for surfing. The beginning of the following week gets bigger – Monday the 13th sees 10ft to 12ft NW swell with a ton of energy – but with a strong cross-shore wind, it's total chop. By Tuesday the 14th, the swell drops back to 2ft, still with big 16-second periods, but it's clean. Just too small. From the 15th through the 18th, it's pretty much flat, with tiny 0.3ft to 1ft swells and poor conditions.
Now, there's a glimmer of hope later on. On Monday the 20th, we get a 5ft NNW swell with a light cross-off breeze in the morning. The energy is moderate, and it's surfable, but it's just very ordinary. The real standout, and I mean the *only* true standout in this whole 16-day window, jumps out on Tuesday the 21st. The morning session is looking magic: a clean 7ft NW swell with glassy conditions and a light southerly breeze. The energy is solid, and "expect good surf conditions" is the call. That's the morning to be in the water. It'll drop off in the afternoon as the wind swings onshore.
The second week has one big note of caution and one absolute bombshell. On Wednesday the 22nd, the swell pumps up to a massive 12ft from the NW, with very strong energy. But the forecast is clear: this is predicted to be *too big* for Devonport Rivermouth. It's a solid expert-only session. Then, after a drop-off on the 23rd, we get another potential cracker on Friday the 24th. Early morning looks unreal – 10ft NW swell with glassy conditions, the energy is enormous, and it's noted as "excellent surf conditions for experienced surfers." That's a big swell, long period (9 seconds), clean conditions… perfect for the experienced crew. It's over 8ft, so beginners, stay on the beach for this one. The afternoon drops to a more manageable 6ft but with cross-off winds, still good.
So, for your best bet, pencil in the morning of Tuesday the 21st for a solid, clean session. The real big-ticket day for the experts is the morning of Friday the 24th, but that's a long way off, so keep an eye on it.
