The Lowdown
G'day, Rusty here. Let's be straight with you—this isn't a classic summer run for Cornwall. We've got a long, flat spell ahead, so don't go paddling out expecting much.
The water is sitting at a very unusual 67°, which is 6° warmer than normal for this time of year around Whitsand Bay and Tregantle. That's a proper warm bath, but it won't save the surf.
Tuesday afternoon kicks off with barely a ripple—just 0.3ft of south swell with a very long 16-second period, but the combined energy is weak (8). A south cross-on breeze won't help. This is poor.
Wednesday the 22nd stays tiny. Morning has a north cross-off breeze that keeps it clean, but the swell is still a pathetic 0.3ft. The afternoon gets glassy with a touch of SW wind, but again, nothing to ride.
Thursday the 23rd is the same story—0.3ft from the south, light cross-shore winds, and no energy. Friday the 24th offers glassy morning conditions but still 0.3ft with a period of 13 seconds. The afternoon turns onshore.
Saturday the 25th sees a bump of 2ft from the west, but it's short-period slop at 3 seconds (energy 9) with a fresh cross-onshore breeze at 19 mph. That's lumpy and hopeless.
Sunday the 26th brings a slight increase to 3ft from the west, period only 4 seconds, and energy at 25. Winds are cross-shore and moderate, but this is still poor surf.
Monday the 27th drops back to 2ft in the afternoon with a cross-onshore wind. The entire first week is a write-off.
We then hit a massive gap. From Tuesday the 28th through to Friday the 31st, the swell is 0.3ft to 2ft at best, with strong onshore winds and rain. Saturday the 1st of August finally shows a pulse—1ft from the WSW with a 10-second period and energy at 37. Winds are moderate cross-shore. It's still poor surf quality, but things start to look lively.
Sunday the 2nd of August is the closest thing to a standout in this whole outlook. Swell builds to 4ft from the SW, period is short at 5 seconds, but the combined energy reaches 98—moderate energy, finally. However, winds are fresh cross-shore from the WNW at 19 mph, creating lumpy cross-chop. This is borderline too big for beginners at 4ft, and with the short period and messy wind, it's not a clean day. Still, it's the biggest swell of the window.
Monday the 3rd drops to 2ft from the SW with a light cross-onshore breeze. Tuesday the 4th has clean conditions with a light east cross-off breeze and 1ft from the SW, but again, nothing exciting.
From Wednesday the 5th onward, it's back to tiny, onshore slop.
The best to be had is that Sunday the 2nd of August bump at 4ft, but with the short period and fresh cross-shore winds, it's a messy, lumpy affair. For a sand-bottom beach, that short-period west-northwest windswell is going to close out and crumble. Honest truth: this setup looks more interesting for kite surfing than paddle surfing.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Whitsand Bay and Tregantle 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.
