Lake Erie Harmful Algae Bloom (HAB) Forecast

The National Centers for Coastal Ocean Service NCCOS provides a forecast of the Microcystis harmful algal blooms (HABs) in Lake Erie several times a week during the warmer months of the year. HAB forecasts are based on understanding the causes of HABs and how they respond to changing weather and ocean conditions. The other critical component of a HAB forecast is the ability to routinely and remotely detect HABs, their toxins, and environmental conditions that foster blooms and enhance their toxicity. The 2024 season is now closed and the HAB 2024 Final Assessment is now posted.  Once the 2025 season commences the reports will be posted here.
