HARMFUL ALGAL BLOOM FORECASTS
Texas Satellite Imagery
Composite 8-days of satellite imagery up to 10-07-2026
showing location of algae bloom which may include algae besides K. brevis.
Water samples from 09-30-2026 to 10-07-2026 detected red tide (caused by Karenia brevis) along the coast at levels that pose a respiratory irritation risk in Brazoria and Nueces counties and at levels unlikely to cause respiratory irritation in Aransas and Calhoun counties.

The image was derived from Copernicus Sentinel-3 satellite data from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and was processed by NOAA, National Centers for Coastal Ocean Science. NOTE: Image quality will vary with clouds and satellite position (OLCI satellite background information). Cell count data were provided by several contributors.
