Where
This pip is that mark on this tide — not the day on the ring.
- 8.7
Boca Paila
sand dropoff · public structure · mid
Named inlet north of Ascension. Permit and a tarpon on the dump. Public geography.
- — sand dropoff on a outgoing tide is a classic match.
- — In-play: Permit, Bonefish, Tarpon.

Punta Allen / Ascension flats
hard flat · public structure · skinny
The village and the bay. Bones and permit. Sian Ka’an biosphere — lodge rules, not a freelance wade across the reserve.
- — hard flat on a outgoing tide is a workable match.
- — In-play: Bonefish, Permit, Tarpon.

When
When is moving water in a good hour — not the day. First light and last light are named when the clock is the story. Today’s ring mixes the best mark, the lead fish, and the best window, then taxes the sky. A strong incoming can sit under a weak day if the wind or the fish is off. Calendar cells are a third recipe: range, moon, and the day’s forecast.

Why — and who
- — Tide is outgoing (modeled — no NOAA gauge on this water).
- — Clear. Sky is workable.
- — Wind 5 mph E. Castable. Sight-fishing is on if the sun is out.
- — New moon — spring tide range. Sight water often prefers a moderate range and clean water over a huge spring.
