The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up for the Bay of Martyrs. This is a reef break that’s really only for the advanced crew, and it’s inconsistent, so you need to pick your moments. The water temp is about average for this time of year, nothing weird going on.

The good news is there’s a solid run of surf starting Friday, August 21st, but it’s not all clean. Friday morning kicks off with 10 ft swell from the WSW, period 15 seconds, and cross-off wind – clean enough – but the energy is already pumping at 4294 (moderate-strong). The afternoon stays similar but a bit stronger wind. The real standout starts Saturday the 22nd. The swell jumps to 15 ft from the SW, period 14-15 seconds, and the energy is massive at 9043 (very strong). It’s a cross-shore breeze, so it’s not perfect, but for the advanced crew, that’s a session. However, at 15 ft, this is strictly for experts only.

Sunday the 23rd is the best of the early window. The swell drops slightly to 12 ft from the SW, but the period extends to 14-16 seconds, and the energy is still strong at 5629. The wind goes light to gentle cross-off, making it clean. That’s a proper day for the experienced surfer.

Monday the 24th still has some good leftover swell, 8 ft with offshore wind in the morning – clean and solid. But from Tuesday the 25th through Wednesday the 26th, it goes to onshore junk, with scores hitting zero. That’s a complete write-off. Thursday the 27th sees a drop in size to 5 ft, with a weird 21-second period in the afternoon – that’s a very long groundswell, which can make a reef like this fat and hard to time. Still, the energy is moderate.

Friday the 28th and Saturday the 29th are back to onshore wind and poor conditions, with no real surf to speak of. Then from Sunday the 30th of August, things turn around. The swell drops to 3-4 ft from the WSW, but the wind goes offshore, clean, and the energy is low (516-477). That’s a small, glassy day for the longboard or a fun little wave when the tide’s right.

Monday August 31st brings a slight increase to 4 ft, still offshore, and the energy picks up to 1267. The conditions are clean and the swell is from the SW, which is the optimum direction for this break. That’s a solid day for experienced surfers.

Tuesday September 1st has 6 ft from the SW, period 15 seconds, and light cross-off wind – clean again. But the afternoon goes cross-shore and bumpy. Wednesday 2nd and Thursday 3rd see the swell building back to 10-13 ft, with clean conditions in the morning. Friday September 4th is the big one in the second week: 13 ft from the SW, period 18 seconds, and energy at 10640 (very strong). The morning is clean with cross-off wind. That’s a huge, powerful swell – experts only, and you’ll want to be on it early before the wind shifts.

Saturday September 5th drops off to 8 ft with onshore wind, so the window closes.

Overall, the standout is Saturday August 22nd to Sunday August 23rd for the biggest, most powerful swell, but Sunday the 23rd gets the nod for cleanliness. Later on, the mornings of Monday August 31st and Friday September 4th are top-tier for experienced surfers.

Rusty.
