When is high tide flooding most likely at this coast?
Check the next 30 days of NOAA high tide (sunny-day) flooding likelihood for a supported coast, then compare the model outlook with current NWS coastal alerts.

Looking for the highest-likelihood source rows in the next 30 days and the current NWS coastal-alert state.
Use the model for dates. Use NWS for current hazards.
NOAA describes daily likelihood relative to an established local flood threshold. A higher percentage means the modeled tide/seasonal water level is closer to exceeding that threshold; it does not mean your exact street or beach has that same probability.
NOAA’s own guidance points users to the National Weather Service for potential coastal flooding within roughly five days because real-time weather can materially change water levels.
