High Tide Flooding Outlook for August 2024

August “higher than normal” tides–and flooding–predicted for Hawaii and some East & Gulf coast locations.

• August’s highest tides will start in many locations around August 17th, although the Atlantic seaboard will see these super high tides a few days later. 
• The Gulf Coast and Hawaii are predicted to also see extreme tides at the very end of the month, and Hawaii is also expected to see them in the first few days of August.
• No high tide flooding is predicted for the West Coast this month, other than in Hawaii.
• Again this month, all 4 of Hawaii’s biggest islands are predicted to see higher than normal tides, with both the “Big Island” and Maui expected to see LIKELY flooding between August 18 & 19.
• See the details on the locations NOAA’s is predicting possible and likely coastal flooding this month: Northeast, Mid-Atlantic, Southeast, Gulf Coast, and Hawaii. 

About these Predictions: “These flooding likelihoods are derived from a probabilistic model that incorporates tide predictions, sea level rise trends, and seasonal changes in coastal sea level to predict the potential that a higher than normal high tide may exceed established National Ocean Service flood thresholds. During these periods, high tide flooding may occur in flood-prone areas.” NOAA
