The Lowdown
Alright, let’s break down what’s going on for the next couple of weeks.
First up, Black Rocks Jetty has a slow start. Tuesday the 1st is surfable but nothing special – a small 3ft S swell with a light breeze. Wednesday the 2nd is glassy but tiny, with a 1ft SW swell in the morning and a 3ft SE swell later. Thursday and Friday stay small and weak with poor conditions.
The first real standout is Saturday the 5th of September. The morning brings a clean 5ft SW swell with a long 14-second period and glassy conditions. The combined energy is solid at 1002. This is excellent for experienced surfers – clean, lined up, and that groundswell will work beautifully on this reef. The water is a touch warmer than normal at 77°F. Crowds are possible here, so keep that in mind. Saturday afternoon stays glassy with a 5ft SW swell too – a great day.
Sunday the 6th and Monday the 7th are okay but not as clean, with cross-off and onshore winds creeping in. Monday afternoon gets messy with a 30 km/h onshore wind.
Tuesday the 8th of September is a big one – but only for experts. We’ve got a 13ft to 15ft SSW swell. The combined energy is massive at 9524, but the wind is fresh and cross-shore, making it lumpy. Anything over 8ft is for experts only – this is more of a kitesurfing day. Wednesday the 9th still has a big 12ft to 10ft swell, but the afternoon cleans up with a light cross-off breeze.
Thursday the 10th of September is another cracker. The morning is glassy with a 7ft SSW swell – excellent for experienced surfers. The afternoon stays glassy with a 6ft SW swell. Clean and solid.
The second week drops off but stays clean. Friday the 11th is glassy all day with 5ft to 4ft SSW swell. Saturday the 12th has a clean afternoon with a 5ft SSW swell and offshore wind. Sunday the 13th is a mellow day with tiny 3ft to 2ft glassy waves.
Then Monday the 14th of September brings a late pulse of 8ft S swell with a short 11-second period. The afternoon is glassy, which is excellent for experts. After that, the surf fades quickly through Tuesday and Wednesday with onshore winds and weak waves – not worth the effort.
The best days to plan for: Saturday the 5th for clean 5ft glassy conditions, and Thursday the 10th for a glassy 7ft SSW swell.
Stay stoked,
