Alright, Rusty here again, breaking it down for our imperial-minded crew.
Fish Boma has a steady run of southerly groundswell coming our way, so you won't be sitting on the beach for long. Water temp is 62°F, about normal for the season.
Monday the 6th, we’re in the water with 6ft of swell from the SW, a slight cross-off wind from the ENE at 3 mph. The wave energy is strong at 1113. This is an experienced surfer’s wave – a bit too much grunt for beginners. The reef is exposed and the period is 12 seconds, so the lines will be clean. Expect some company; crowds pop up sometimes.
Tuesday the 7th is where it’s at. The morning serves up 6ft of SW swell with a glassy wind from the WNW at 3 mph. Energy at 1133. The afternoon holds 6ft with a glassy SSE wind at 3 mph. Best couple of days.
Wednesday the 8th turns messy. Swell at 7ft from the SW, but a cross-onshore wind from the W at 9 mph puts chop on the face. Energy climbs to 1859, but the surface gets lumpy.
Thursday the 9th is massive – 10ft of SSW swell with a 14 second period. Energy at 3178. The wind is light cross-on, but this is expert-only territory. Way too big for beginners.
Friday the 10th is a classic. Still 10ft of SSW swell, but the morning gets a clean cross-off wind from the E at 6 mph. Energy peaks at 3372. The swell direction matches the optimum S angle, and the wind keeps it tidy. This is the big-wave highlight.
After that, it tapers off. Saturday the 11th gives us 7ft glassy in the morning, Sunday the 12th drops to 5ft calm. Both are solid, user-friendly days.
Early the next week, Monday the 13th and Tuesday the 14th are smaller, 4ft to 5ft, clean but not punchy. Wednesday the 15th goes flat with 3ft and strong wind – skip it.
Thursday the 16th sees a small 4ft glassy morning from the SW, nothing to write home about.
Looking into the second week, Sunday the 19th is a big one – 8ft of SW swell, glassy, energy at 1695. Then Tuesday the 21st is the standout long-range call: 8ft, zero wind, energy of 1761 in the morning and 2012 in the afternoon. That afternoon session is promising – powerful, glassy, and empty due to the size. Crowds are likely when it’s this good, but the swell will filter out the faint-hearted.
No real flat spells here. The best windows are the 7th, the 10th, and the 21st.
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.
