Actions

Steps your workflow can run in NOAA Tides & Currents.

Get water levelsRead the water level measured at a tide station: the latest reading, today's, or any period you name. Choose the 6-minute series for the live gauge, the hourly series for verified history, or the 1-minute series for storm detail. Heights come back against the datum you pick, so they read the same way a tide table does. No API key required.

Get high and low watersRead the high and low waters that actually happened at a station - when each tide turned and how high it got, with the higher high and lower low of each day marked. This is verified data, published about a month in arrears; for the tides still to come, use Get tide predictions. No API key required.

Get daily highest and lowest levelsRead the highest and lowest water level of each day at a station, with the time each happened and how complete that day's record was. Verified data - the quickest way to find the worst day of a storm, or to chart a season. No API key required.

Get mean water levelsRead a station's monthly means - mean sea level, mean high and low water, the month's highest and lowest, and the tidal ranges - going back as far as the station does. Great Lakes stations can also be read as daily means. This is the series long-term change is measured in. No API key required.

Get tide predictionsRead predicted tides for any of NOAA's 3,500 prediction stations: the high and low waters with their times and heights, or the whole curve at an interval you choose. Works for dates years ahead, so it answers 'when is high tide on Saturday?' as easily as it fills a year's tide table. No API key required.

Get bridge clearanceRead the air gap - the clearance between a bridge and the water beneath it - at the bridges NOAA measures, which is what a ship's master checks before passing under one. Measured from a fixed point on the bridge, so no datum applies. No API key required.

Get forecast model water levelsRead water level guidance from NOAA's Operational Forecast System models - the nowcast and forecast for a station, at 6-minute steps. Where the gauge tells you what the water is doing, this tells you what the model expects it to do next. Available at real-time stations inside a model's area, from 2020 onwards. No API key required.

Get weather and water conditionsRead what a tide station's other sensors report: air and water temperature, wind speed, direction and gusts, barometric pressure, humidity, visibility, conductivity, and salinity. One action, one measurement at a time. Which sensors a station carries varies, and a measurement it does not record comes back empty rather than failing. No API key required.

Get measured currentsRead how fast the water is moving and which way, from one of NOAA's current meters. Each meter records at several depths, so pick a bin or take the one the station publishes by default. Covers meters deployed now as well as retired and survey deployments. No API key required.

Get current predictionsRead predicted tidal currents: when the flood and ebb run hardest, when the water goes slack, and how fast it runs in between. Slack water is what you plan a transit or a dive around. Covers 4,000-odd prediction stations, for any date. No API key required.

Get current meter statusRead a current meter's own housekeeping record for a period: which way it is pointing, its pitch and roll, the water temperature and pressure at the instrument, and its battery voltage. This is how you tell a station that has stopped reporting from one whose mooring has shifted. No API key required.

Find stationsFind CO-OPS stations by name or state and get the id every other action takes, along with their coordinates and which networks they belong to. Pick the collection you need - active water level gauges, tide prediction stations, current meters, weather sensors, and more. No API key required.

Get a stationRead one station's record - where it is, what it is affiliated with, which resources it publishes - and optionally fold those resources straight in, so its datums, sensors and flood thresholds arrive in the same step. No API key required.

Get station metadataRead one piece of a station's reference data: its tidal datums and the epoch they belong to, its harmonic constituents, its sensors and their status, its NOS and NWS flood thresholds, its survey benchmarks, its prediction offsets, or a current meter's depth bins and deployments. No API key required.

Find nearby stationsList the stations within a given distance of another one, nearest first, with what each measures. Use it to find the gauge nearest a harbour, or a fallback when a station goes quiet. No API key required.

List PORTSList every PORTS - the Physical Oceanographic Real-Time Systems NOAA runs at major US seaports - with the two-letter code the other PORTS actions take. No API key required.

List PORTS stationsList the stations that make up one PORTS, with the id and position of each - the water level gauges, current meters and weather sensors a port is watched with. No API key required.

List PORTS plotsList the plots CO-OPS publishes for PORTS stations - which chart is drawn for which station, and the image it is published as. No API key required.

Get PORTS live readingsRead every live reading from one PORTS in a single call: water level, wind, air and water temperature, pressure, visibility and currents from every sensor in the port, all timestamped together. This is the screen a harbour pilot checks before a transit. No API key required.

Check service statusCheck whether CO-OPS is running in Continuity of Operations mode, when it serves from its backup site and some products are reduced. A scheduled workflow can check this first and hold off rather than recording a gap as real data. No API key required.

Get sea level trendRead how fast sea level is changing at a station, measured from its own record: the trend per decade, the confidence interval on it, and the years it was fitted over. Leave the station blank for every station NOAA publishes a trend for, US or global. No API key required.

Get observed sea level recordRead the observed sea level record a station's trend is fitted to - the trend itself, the seasonal cycle, and optionally the whole monthly mean series behind it. Choose the current tidal datum epoch or the most recent 30 years. No API key required.

Get sea level rise projectionsRead how much sea level is projected to rise at a station, by decade and by scenario, from the US Interagency Sea Level Rise Task Force report - Low through Extreme, each with its confidence interval. The offsets dataset returns the reference levels those projections are stated against. No API key required.

Get record water levelsRead the ten highest water levels ever recorded at a station, with the storm that caused each one and how it was measured. The answer to 'has it ever been this high before?'. No API key required.

Get storm peak water levelsRead the named storms of a year, then the peak water level each station recorded during one of them. Name a year to list its storms and their event ids, then feed an id back in to see what the water did along the coast. No API key required.

Get extreme water levelsRead the highest (or lowest) water level of every year, or every month, in a station's record, detrended so the years can be compared. Optionally add the exceedance levels - the height expected to be passed once a year, once a decade, once a century. No API key required.

Get flood level probabilitiesRead how likely a given water level is at a station: the levels expected to be exceeded once in 1, 5, 10, 50 and 100 years, with confidence intervals, from NOAA's regional frequency analysis. This is the number a design or insurance question turns on. No API key required.

Get daily flood daysRead, day by day, whether a station flooded and how high the water got: the day's peak level, the hour it happened, and whether minor, moderate or major flooding was reached. High tide flooding is the sunny-day flooding that closes a road at high water. No API key required.

Get flood day countsCount how many days a station flooded, summarised by calendar year, by month, by season, or by meteorological year - the May to April year that keeps a winter's floods together. The record summary instead returns the worst year on record and how many flood days were typical in 2000, for comparison. No API key required.

Get annual flood outlookRead how many days of high tide flooding a station is expected to see this meteorological year, as a low-to-high range, with when the outlook was issued and how it was computed. NOAA publishes it each May. No API key required.

Get flood day projectionsRead how many days of flooding a station is projected to see in a future decade, under each sea level rise scenario - or the narrower range now judged most likely. The number a planning or resilience case is built on. No API key required.

Get flood likelihoodsRead how likely high tide flooding is at a station over the coming year: the chance for each day, or the peak day of each month, with how far the predicted tide sits below the flooding threshold. This is the forecast behind NOAA's High Tide Bulletin. No API key required.

Get regional flood outlookRead NOAA's written high tide flooding outlook for a stretch of coast: which dates to watch this month and why, in plain English. Ready to drop straight into a newsletter or an alert. No API key required.

Get benchmark elevationsRead a survey benchmark's published elevation and the datums measured from it - the fixed marks a tide station's heights are ultimately tied to, used when a gauge is re-levelled or replaced. Take the benchmark number from a station's benchmarks. No API key required.

Get annual current predictionsRead a whole year of tidal current predictions for one station in a single step: every slack water and every maximum flood and ebb, in order. This is the annual current table, the same one NOAA publishes as a report. No API key required.
