SYNTHORA NOAA Tides – Tide & Water Level with Storm-Surge Anomaly
x402
SYNTHORA NOAA Tides – Tide & Water Level with Storm-Surge Anomaly is a paid API for AI agents from api.hergertsynthora.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).
Fetches live NOAA CO-OPS tide and water level data for US ports/stations and computes the anomaly between observed and harmonically predicted values to surface storm-surge and port-disruption signals.

How this service works
SYNTHORA noaa-tides: tide and water level for US ports/stations, VERIFIED by crossing NOAA harmonic prediction with the LIVE observation at the same station — the anomaly (observed minus predicted) is the storm-surge/port-disruption signal. Source: NOAA CO-OPS official, free, no key. $0.005 USDC x402 Base.
Output
Returns the current observed water level and NOAA CO-OPS harmonic tide prediction for the requested US port or station, along with the computed anomaly (observed minus predicted) which serves as a storm-surge or port-disruption signal. Positive anomalies indicate water levels higher than expected, potentially signaling storm surge or coastal flooding conditions.
Example use cases
Storm surge alert before cargo departure
“Before we dispatch the container ship from the Port of Houston today, can you check the NOAA tide data and tell me if the observed water level is significantly above the predicted tide — I need to know if there's a storm-surge anomaly that could affect berthing.”
Coastal flood risk check for port operations
“Is there any unusual water level anomaly at the Port of Miami right now compared to NOAA's harmonic tide prediction? I'm trying to assess whether dock operations are at risk of flooding.”
Maritime route disruption monitoring
“Check the tide and water level situation at the Port of Seattle — give me the current observed level, the NOAA predicted level, and flag whether the difference suggests any storm surge or port disruption.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/noaa-tidesWhen to prefer
Use this endpoint when you need both the raw NOAA tide/water level data AND an anomaly signal computed against harmonic predictions in a single call — ideal for maritime operations, port logistics, storm-surge monitoring, or coastal risk assessment at US ports. Prefer this over raw NOAA API calls when you want the observed-minus-predicted delta pre-computed without building your own harmonic comparison pipeline.
Side effects
- Station not found or invalid station identifier returns an error
- NOAA CO-OPS live observation unavailable for the requested station at that moment
- No recent observation data available for remote or inactive stations
- Ambiguous station name matching multiple locations
- Network timeout when fetching live NOAA data
