Marengo Surf Forecast and Surf Report

Alright, let’s get into it. We’ve got a solid window of surf coming up at Marengo, a reef and point setup that’s fairly exposed to the swell, so it’s got a decent amount of pull. The water temp is sitting about average for this time of year, nothing wild there.

The real standout is the start of the period. Thursday the 16th kicks off with a strong pulse of SW groundswell, 8ft, 15 seconds, and the combined energy is massive at 2457. That’s a lot of power. The wind is light and cross-off for the morning, and that’s a big positive for clean lines. Afternoon sees the wind swing offshore, still light, so it’s going to be clean all day. This is solid, powerful surf – not for the faint-hearted or beginners. This is for experienced surfers only.

Friday the 17th keeps the run going. Swell drops a touch to 7ft, but the period stretches to 16 seconds, so the energy is still huge (2003). The morning is clear with a slight cross-off, and the afternoon gets glassy with WSW wind dropping to almost nothing. That’s about as good as it gets for a point/reef break. This is the pick of the bunch.

Saturday the 18th sees the swell fade to 4ft, energy dropping to 648. The morning is cross-shore, but the afternoon glass-off with calm wind and 4ft of SW swell. It’s a good little session for the lighter boards.

Sunday the 19th is small, 2ft, but glassy as glass both sessions. The energy is low (335), so it’s a longboard or funboard day. The wind is calm or slight, so the surface will be like a mirror.

From Monday the 20th through to Thursday the 23rd, we’re in a lull. Swell sits around 2ft to 4ft, energy stays under 500. The wind is mostly cross-off or offshore, so it’s clean, but the waves are small. The 21st and 22nd have some glassy moments, but it’s not firing.

Now, pay attention to the end of the week. Friday the 24th into Saturday the 25th, a new SW swell builds quickly, 7ft to 8ft, with strong energy (1784-2267). But the wind picks up too – fresh breeze from the WSW, cross-off. The conditions are marginal, with a lot of wind on the surface. This is more for the experienced crew who don’t mind a bit of chop.

Sunday the 26th looks much better. The swell drops to 6ft, but the wind goes light offshore from the WSW, and the energy is still a solid 1068. Afternoon gets a gentle offshore breeze, and the waves are clean again. This is a good session for the weekend.

Monday the 27th and Tuesday the 28th see another pulse of 7ft to 7ft SW swell, but the wind is cross-off and then cross-shore, getting stronger. The energy is high (1577-1684), but the chop from the wind will make it bumpy. Not the best for clean surfing.

Then we hit a bit of a slump. Wednesday the 29th morning is cross-onshore and poor, but the afternoon gets glassy with a calm wind and a 5ft SW swell, energy 873. That’s a sneaky good session if you can get out.

Thursday the 30th and Friday the 31st are smaller, 3ft to 4ft, but the wind is moderate offshore, and the period on Friday gets long at 17 seconds, energy 874. That’s a clean, long-period groundswell, perfect for the point.

So, the best on offer is without a doubt Thursday the 16th and Friday the 17th. That’s the big, clean, powerful groundswell. After that, Sunday the 26th is a solid second choice. The rest is small stuff or wind-affected. Keep an eye on the last day of the month, Friday the 31st – that long-period swell with offshore wind could be a real treat.
