The brief answers three questions: where on this water, when the tide is moving, and why — tied to a gauge, not a vibe. The calendar is the same engine stretched across a month.
Example
not a bite guarantee
Observed
— NOAA CO-OPS tides, observed water, station wind and water temp
— NWS hourly (U.S., including Puerto Rico) and Open-Meteo (Bahamas, Mexico, Seychelles)
— USGS GNIS names — pins snapped to Feature IDs when the hydro layer has them
— NOAA ENC wrecks and FKNMS legal polygons
Inferred
— Habitat × tide: flood the grass, drain the creek, wrecks on the fall
— Wind setup/setdown: observed minus predicted. On Texas this often is the tide
— Species thermal windows and seasonal peaks
— Bahamas and Mexico tide is a modeled M2 — labeled, not a gauge
Method tax
— Fly and kayak pay above ~16 mph
— Wade needs standing water
— Skiff loses skinny flats at dead low
— Jetty likes midday current. Spin is what you do when the day does not allow the fly
— Offshore (troll / deep jig) wants wind a boat can stand and hides the grass marks on purpose
Official layers we still want live
TPWD coastal ramp inventory via TxGIO (data.geographic.texas.gov). TPWD Coastal REST still requires a token. Access pins here are curated from the published launch directory.
Texas GLO Beach & Bay Access from glo.texas.gov. Hub item is cited; a public REST query was not open without their token.
NPS Padre Island driving/camping closures — nps.gov/pais. We cite the rule; the park API needs a key.
Scores are 1–10. They are not bite guarantees. A 9 in August heat still means go early. A 3 after a norther still holds fish in the gut if you already know the water.
