On This Water

Mexico · Isla Mujeres / Cancún bank

Sailfish are in the mix — the Cancún / Mujeres bank — sail on the current, not a bonefish morning.

Winter sailfish capital. The fleet works the Yucatan current north of Cancún. Mahi on the weed in summer. This is a troll-and-kite desk, not a bonefish brief. Modeled tide, Open-Meteo wind.

  • This brief is for 2026-08-19, not this morning. Wind is a forecast. Observed water versus the table is a today-only instrument.
  • Mexico requires a CONAPESCA license. Sian Ka’an, Contoy, and Espíritu Santo are park or biosphere water — verify before you fish.

No FKNMS polygon in this box. Mainland Florida, Louisiana, Texas, Mexico, and the Bahamas are not Keys sanctuary closures.

Why — and who

  • Tide is incoming (modeled — no NOAA gauge on this water).
  • Clear. Sky is workable.
  • Wind 10 mph ENE. Castable. Sight-fishing is on if the sun is out.
  • Waxing crescent moon — neap tide range. Offshore wants bait and current more than a skinny tide.
