Alright folks, Rusty here. Let's talk about Fish Boma for the next couple of weeks. We've got a decent SSW groundswell pulse rolling in, but early on it's a bit messy. The water's sitting at 62°, pretty darn normal for this time of year, so no surprises there. The main window to circle on your calendar is Friday morning, July 10, and then again on Thursday morning, July 23 – those two are the real standouts.
Overall pattern:
We start off Wednesday afternoon (July 8) with a solid 8ft SSW swell (12s period) but a cross-on WSW breeze makes it choppy. That 12 mph wind isn't doing us any favours, and the combined energy is pumping at 4316 – a lot of juice, but messy. Thursday (July 9) stays big (10ft SSW, 14s) but still cross-on, though lighter wind Thursday morning gives a slight improvement. Still not clean.
Then Friday morning (July 10) – bingo. The wind swings NNW, light (6 mph) and cross-off, cleaning up that 10ft SSW swell (13s). The combined energy is 3130 – still strong, but the shape should be excellent for experienced surfers. This is the first real highlight: solid 10ft waves, good direction (SSW) matching the optimum S, offshore wind, and the reef setup should handle that period well. Crowds are possible (sometimes), so get in early.
Saturday morning (July 11) stays clean with E 6 mph cross-off, but the swell drops to 8ft (12s) and energy down to 1746. Still good fun, but not the highlight. Sunday morning (July 12) is smaller again at 5ft (11s), clean with ENE 6 mph – nice for intermediates.
Then we hit a lull. Monday (July 13) through Tuesday (July 14) sees a shift to weak ESE swell (8s) and onshore winds – poor to marginal. Wednesday (July 15) gets glassy with light variable wind, but the swell is tiny (3-4ft, 8-9s) – not worth paddling out for. Combined energy drops to 223-270, weak.
Thursday (July 16) brings another SSW pulse, but it's accompanied by strong W winds (22 mph) and rain – just nasty. Friday (July 17) cleans up nicely with E 12 mph cross-off, swell 7ft SSW (12s) and energy 1436 – a good option if you missed the earlier window, but the wind is a bit stiffer, still clean though.

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.
