La Ventana: find your window
La Ventana means "the window." On the Sea of Cortez it has two: calm, clear summer mornings for spearfishing, and the winter El Norte wind for kiting and wing. Built from 0 hours of wind, swell, and water data plus 0 fish sightings. They run opposite each other; pick an activity to see when.

Wind, gusts, and air come from the Open-Meteo high-resolution historical archive (the coarse ERA5 reanalysis misses the channeled El Norte wind); waves, swell, and water temperature from the Open-Meteo marine archive, both 2022-2025. Water clarity is derived from NOAA satellite chlorophyll-a (MODIS-Aqua monthly, 2003-2022): plankton greens the water and cuts visibility, so clearer water is lower-chlorophyll water. The default fish view predicts each species' season from its preferred water-temperature band (FishBase) matched to the SST climatology, which is robust where sightings are thin; the sightings views are GBIF occurrence records for the waters around southern Baja California Sur (all years). Marlin pools the billfish; yellowtail pools both Seriola species. Sightings are a presence proxy, not catch logs. All sources are open and free.
The sliders are the point
This is a scenario engine: thresholds go in, a recomputed year comes out, live in your browser. Swap wind limits for staffing levels, rate floors, or covenant triggers and the calendar becomes your planning model.
