The Lowdown
Alright, let’s do this in feet and miles.
First up, we’re looking at Spanish Bay-South Moss. This is a spot for the advanced crew – fairly consistent, but you’ll be sharing the water sometimes. The water temp is about average for this time of year, nothing wild there.
The pattern across the 16 days is pretty mellow, with a lot of small, clean-ish windows but nothing that screams "drop everything and go." The first few days – from Saturday the 18th through to the end of July – we’re seeing mostly small swell around 2ft to 3ft, coming from the WNW or SSW. The combined energy is moderate, sitting in the 250 to 700 range (moderate wave energy). The wind is mostly light and offshore or cross-onshore, which keeps things reasonably clean, but the wave comment keeps saying "marginal surf forecast or questionable tide conditions" – so it’s not going to be firing.
The mornings are generally the better call with that offshore wind (NW or WNW), giving you glassy or clean conditions. Afternoons get a bit more cross-onshore chop, especially from the 19th onwards. The swell period is long – 14 to 17 seconds – which means groundswell, better shaped waves, but longer waits between sets. That’s good for a point break or reef, but this is a beach setup, so it might break a bit too straight.
Now, the standout window – if you’re patient – is around Saturday the 25th and Sunday the 26th. On Saturday the 25th, the morning has 3ft SSW swell with a 21-second period and combined energy of 1161 (strong wave energy). The wind is offshore NW at 9 mph – clean. Sunday the 26th holds similar: 3ft, 19-second period, 1242 energy, again offshore NW. These are the best on offer, but even then, the wave comment is still "marginal." It’s not a total washout, but don’t expect a classic.
Into the first week of August, the swell picks up a bit – 5ft to 6ft from the NW on the 31st and 1st of August, but the period drops to 9 seconds, so it’s shorter period, weaker shape. Wind is cross-onshore, so it’ll be a bit bumpy. The energy is still moderate (around 550-730). Not great.
Overall, there’s no real "best day" that stands out as a classic. The 25th and 26th July mornings are your best bet – small but clean, with that long-period groundswell. Just keep your expectations in check.
