    Monthly High Tide Outlook

    This tool provides visualizations for when and where above-normal high tides and high tide flooding may be experienced, up to a year in advance. 

    Coastal flooding likelihoods are derived from tide predictions, sea level rise trends, and seasonal changes in coastal sea level. Likelihoods represent the potential that a higher than normal high tide may lead to at least minor coastal flooding in flood prone areas. Real-time weather conditions may still cause flooding outside of dates identified in this product.
