The Lowdown
Alright, let’s look at this span for Topaz Street. Honestly, it’s a tough outlook – small surf and messy conditions will have you checking the forecast more than the water. Water temp is about normal for this time a year.
First real shot is the morning of Saturday, 14th September. Tiny 2ft swell from the west, period a short 7 seconds, so it’s weak windswell with combined energy of 130. Winds are cross-off from the southeast at 12 mph, so the surface will look clean, but don’t expect much push.
The standout in the whole window is Wednesday morning, 18th September. Still small – 2ft from the south-southwest – but the period is a quality 17 seconds. That’s a long groundswell, giving those waves some life and shape even at that height. Combined energy hits 217, moderate but felt. Winds are light from the SSE at 6 mph, cross-off, glassy. This is your morning.
From Wednesday afternoon onward, it’s a long grind. The swell hangs around 2ft to 2ft from the southwest, but the wind turns cross-on or onshore most afternoons, reaching 12 mph. A few mornings remain clean with light cross-off or cross-shore breezes, like on 22nd and 23rd September, but the waves come up as only marginal. The last chance is Monday morning, 30th September – 2ft southwest groundswell, 15-second period, cross-off breeze, and combined energy of 363, which is the biggest push of the whole stretch – but the call is still “marginal.”
Topaz Street does get busy often, so on those few clean windows, expect a lineup. It’s fairly consistent, so folks will be out.
Best move: Wednesday morning, 18th September. Long period, light wind, clean. After that, it’s a long dry spell.
