Spanish Bay-South Moss Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s talk about what’s coming up for Spanish Bay-South Moss. Honestly, looking at the whole 16-day window, there’s no standout true gem here—nothing that screams “drop everything and go.” The pattern is a long stretch of messy, onshore or cross-onshore winds and poor surf quality, with a few flickers of hope toward the very end of the period. The water temperature is sitting at 60°F, which is a touch warmer than normal for this time of year, so that’s alright if you’re suited up.

We start off on Wednesday, July 8, with a 3ft SSW swell, a 16-second period, onshore WNW winds at 16 mph, and weak combined energy (929). Conditions are poor. Not worth paddling out. That sets the tone.

Thursday, July 9, through to Wednesday, July 15, is a tough run. Swell heights bob between 5ft and 8ft, mostly from the NW or WNW, with periods of 8 to 9 seconds. The winds are onshore or cross-onshore, ranging from 9 to 19 mph. The combined energy stays moderate (371 to 783). Every entry says “poor surf conditions” or “marginal.” The surf quality is just not there. On July 11, Saturday afternoon, it’s a gentle cross-onshore and fairly choppy. On July 15, Wednesday afternoon, the wind picks up to 19 mph with a 8ft NW swell—that’s getting too big for beginners and the wind is fresh, so the setup looks more interesting for kite surfing than paddle surfing.

On Thursday, July 16, and Friday, July 17, we see a slight bump in combined energy (1085 and 1026), but it’s still marginal. Swell heights are around 7ft and 6ft, WNW, with 9-second periods. Winds are lighter on Friday, 6 mph, but cross-onshore with small wind ripples. Still not good.

Now, Saturday, July 18, and Sunday, July 19, bring a shift. Swell drops to 3ft, but the period jumps to 17 seconds (very long period groundswell) from the WNW. The combined energy is moderate (924 and 711). Winds are light, 6 mph, onshore on Saturday morning, but Sunday morning is onshore as well. The surf is marginal, but the long period could mean some clean lines at the right tide. The caveat with such a long period at a beach break is it can break too straight, but Spanish Bay is exposed to the swell. It’s a little promising, but not a standout.

The best on offer looks like Monday, July 20, morning. The wind goes glassy—NNE at 3 mph—and the swell is 5ft from the NW with a 9-second period. The combined energy is moderate (599). The forecast says “expect very good surf conditions.” That’s the one to aim for. The swell is small enough for most, and glassy wind means clean conditions. Crowds are possible at this spot, so keep an eye out.

After that, Tuesday, July 21, through Thursday, July 23, tails off again. Swell drops to 3ft from the SSW with 16-second periods, combined energy weakening (416). Winds are light but cross-onshore. The final day, Thursday, July 23, has a 5ft NW swell with 8-second period and light cross-onshore wind. Marginal. Not a call to action.

So, overall, there’s a long gap of poor surf from July 8 through July 15. The only real highlight is Monday, July 20 morning, with glassy conditions. It’s not a world-class window, but it’s the cleanest you’ll get. Keep an eye on the forecasts, because things can change.

Rusty.
