On This Water

Mexico · Ascension Bay / Sian Ka'an

Bonefish should be the day — Boca Paila and the drains; tarpon live in the darker mouths.

Yucatan flats. Bones, permit, and baby tarpon inside Sian Ka’an. Punta Allen is the village. Lodge water, biosphere rules. Tide is a modeled Caribbean clock — there is no NOAA gauge. Not Baja.

  • This brief is for 2027-02-09. No wind forecast that far out — score is tide, moon, and season. Not a copper day.
  • Mexico requires a CONAPESCA license. Sian Ka’an, Contoy, and Espíritu Santo are park or biosphere water — verify before you fish.

Where

This pip is that mark on this tide — not the day on the ring.

  • Boca Paila

    sand dropoff · public structure · mid

    8.1

    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.

  • Punta Allen / Ascension flats

    hard flat · public structure · skinny

    7.7

    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.

When

When is moving water in a good hour — not the day. 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).
  • Waxing crescent moon — mid tide range. Sight water often prefers a moderate range and clean water over a huge spring.
