Updates in hr min s Forecast update imminent
Alright, let’s talk Shark Island (Cronulla). This stretch of coast is getting a solid run of south swell starting this Sunday, July 5th. The water temp is about normal for the season. Sunday morning is the first call – 3.0m S swell, 11-second period, with a fresh offshore wind from the SSW. That means clean, lined-up reef waves. The combined energy is 2127 (moderate to strong). That’s over 2.5m, so this is strictly for the experienced crew. Beginners, sit this one out. The offshore wind will keep it glassy on the face, but the power is serious.
Sunday afternoon drops to 3.0m from the SSE with a longer 13-second period and a cross-off wind. Energy jumps to 3408 (very strong), but the cross-off angle and shift in direction make it less perfect than the morning.
Monday the 6th holds 2.5m SSE swell, 10-second period, cross-off winds. Energy is moderate at 1309-1315. Clean but marginal quality – tide likely an issue. Tuesday the 7th is similar, with energy peaking Tuesday afternoon at 2183.
Wednesday July 8th morning is a big highlight. 2.5m, SSE, 10 seconds, with a fresh SSW offshore wind – described as “fresh offshore and clean.” Energy is a strong 2408. This is a top-tier session for advanced surfers. Despite the data saying marginal, the offshore wind will dial it in.
Thursday July 9th morning sees the size drop to 1.9m, with a gentle offshore wind (SSW, 15 km/h). Energy is 828 (moderate). Conditions are expected to be very good. This is the best window for strong intermediates. Friday the 10th is 1.6m, light winds, but the afternoon goes cross-shore.
Saturday the 11th is small and weak at 1.2m. From Sunday the 12th to Tuesday the 14th, the surf is tiny – energy values from 30 to 206 – with poor conditions. A real dead period.
Wednesday July 15th has a novelty 0.3m swell with a super long 21-second period from the SSE. A reef like Shark Island can produce a few weird ones, but it’s tiny and low energy (132). Not worth a paddle.
Thursday July 16th afternoon sees a return to 1.7m S swell, 10-second period, cross-shore wind, energy 1138. Friday the 17th morning has 1.0m, 12-second period, light cross-off, clean energy at 658. The afternoon turns onshore.
Saturday the 18th and Sunday the 19th are messy with moderate to fresh winds. However, Sunday July 19th afternoon has a moderate offshore wind, 0.9m S swell, 12-second period, energy 335, and “expect good surf conditions” – a sneaky small-wave window.
Monday July 20th morning brings 1.7m S swell, 11 seconds, with a moderate offshore wind. Energy is 651. Clean again, but size is back up for the advanced crew.
The best call of the whole run is Wednesday July 8th morning – fresh offshore wind, solid 2.5m S swell, strong energy. This is prime for experienced surfers. Thursday July 9th morning is the pick for strong intermediates wanting clean, powerful but not oversized waves.
This is a reef break, and the S to SSE swell direction is close to the optimum SE angle, so it should wrap in well. Crowds are possible on the peak, so expect company.
