The Lowdown

G’day, Rusty here. Let’s cut straight to it. The next couple of weeks have some real juice in the water, but you gotta pick your moments. It’s not all gonna be perfect, but there are a couple of windows that are straight-up firing.

First up, Fish Boma (Southern Cape) is the only game in town for this stretch. The water’s sitting at 63°, which is pretty much spot-on average for this time of year, so no surprises there. We kick things off Wednesday morning with a small, weak signal – only 4ft of SSW swell with a 15-second period. The energy’s there (1147), but it’s not gonna get your heart racing. The wind is a light cross-onshore, so it’ll be a bit bumpy. Not worth suiting up for.

Wednesday afternoon the swell jumps to 7ft from the SW, but the wind stays cross-on and the score is still low. Thursday morning gets bigger – 12ft SW – but it’s lumpy with the cross-onshore. Not great. The standout on Thursday is the afternoon. The wind drops to glass, and you’ve got 10ft of SW swell wrapping in. That’s clean, powerful, and the energy is solid (2674). This is the first real chance to get a proper session.

Friday morning is also a winner. Light offshore E wind, 8ft of SW swell, and clean conditions. This is the pick of the first few days. The afternoon gets a bit cross-y, but still rideable.

Then the weekend turns ugly. Saturday and Sunday bring onshore winds, rain, and a jump to 15ft on Sunday afternoon with 30 km/h winds. That’s blown-out chaos – not for paddling. Monday’s also messy with strong winds and lumpy surf. You’re better off doing something else.

The surf starts to settle down again Tuesday the 12th. The swell drops to 4ft, but check out that period – 19 seconds! That’s proper groundswell, and with a light offshore NE wind in the morning, Fish Boma will be clean and lined up. It’s a bit smaller, but the quality is there.

The middle of the week, the 13th and 14th, sees a mix of clean mornings and cross-off winds. Swell stays around 5ft to 7ft, but the direction shifts a bit to the ESE, which isn’t as good for this break. Still, the mornings are clean.

The real standout, the one you circle on the calendar, is Tuesday the 19th and especially Thursday the 20th. The 19th has 10ft of SW groundswell with a 14-second period and glassy conditions in the morning. That’s a proper heavy session – for experienced surfers only at this size. The energy is cranking (3082).

But Thursday the 20th is the one. The swell is forecast to be a massive 20ft from the SW with a 15-second period, and the energy reading is off the charts at 15620 – that’s strong to very strong. The wind is light and offshore, so it’ll look perfect from the beach. However, this is way too big for this break – the notes say it’s predicted to be too big for Fish Boma. This is expert-only, and honestly, at that size, even a reef break like this could be a washing machine. The swell direction is right, but it’s a monster. If you’re not a pro, don’t even think about it. The afternoon will still have 16ft of swell, still too big for most.

Overall, the best bet for a good, clean, manageable session is Thursday the 6th afternoon or Friday the 7th morning. For the brave, keep an eye on the 19th and 20th, but that’s another level entirely.

Rusty.

Information about the Fish Boma Surf forecast

The above surf forecast table for Fish Boma provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Fish Boma can be found by selecting the local surf guide option on the grey menu. Our Fish Boma surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Fish Boma) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Fish Boma may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
