Tide Sensors

data.norfolk.gov | Last Updated 31 May 2024

This data is from five tide stations located in waterways throughout Norfolk: Elizabeth River Eastern Branch at Grandy Village, Little Creek at 20th Bay Street, Lafayette River at Mayflower Road, Mason Creek at Granby Street, and Elizabeth River Main Branch at Nauticus. This data will allow users to track and analyze tide levels in the City of Norfolk. The data is updated daily and encompasses a timeframe of September 30, 2020 to present. Note: At the Mason Creek tide gauge, the water flows through a weir system (small dam) that alters the flow characteristics of the water; data from this tide station will differ from the other four tide stations. Disclaimer: The City is making this data available with the understanding that it has not been reviewed or verified by an expert. Although the City makes every effort to ensure the tide gauges are accurate, we cannot guarantee the calibration or proper functioning of the gauges and accurate recording of measured tide levels at all times. In no event will the City of Norfolk be liable for any damages, including but not limited to loss or damage to property, lost profits, business interruption, loss of business information or other pecuniary loss that might arise from the use of this data. Any use of this data is for general information only and shall not be used for any improper purpose.
