NowCast 2023-2024

NowCast 2023-2024 Predictive Modeling Project

The County of Orange is currently participating in the NowCast project in collaboration with Heal the Bay and Stanford University. The project is operating at multiple beach locations within Southern California during 2023-2024. The NowCast system uses computer models and environmental data to predict daily bacteriological water quality, much like a daily weather forecast. NowCast predictions will be updated daily during the study period. Click here to learn more about NowCast.
