Harmful algal blooms of Karenia brevis, the organism responsible for red tide in the Gulf of Mexico, can impact the health of humans and animal life. The blooms are patchy in nature and the impacts vary by location and throughout the day depending on nearby bloom concentrations, ocean currents, surf conditions, and wind speed and direction. The NOAA HAB-OFS Public Conditions Report identifies whether or not there is a K. brevis bloom. When there is a bloom, the report indicates the general location and provides forecasts of the potential level of associated respiratory irritation. The resources listed below provide up-to-date information about the observed, local beach conditions in Florida and Texas. During a K. brevis bloom, this information may help you find a nearby coastal area that is unaffected. For health information and resources, see the HAB Health Information page.
In the rare event that a K. brevis bloom affects the coastal waters of Alabama, Mississippi or Louisiana additional
