A clean long-period (16–17s) SSW groundswell is holding overnight — chest-high sets on the Cardiff reef, cleanest right at first light on the dropping tide. Dawn is glassy (SE/S 5mph) until the SW sea breeze fills in around 11am, so go early. It's small and long-period, so bring paddle and glide. Not a charge day — a mellow, uncrowded dawn glass session.

Scored for the dawn window (~5:30–9am) before the sea breeze. Ponto runs close behind Tippers; reef-over-beach-break is the tiebreak on a small long-period day.
Days to Watch
Fri–Sat Jul 10–11 — swell backs off slightly but period stays long (12–13s S), so it holds as fun, small dawn sessions through the weekend off-days. No W/NW event on the board to wake Blacks up yet.
