| Name | Description | Schema |
|---|---|---|
noaa_get_water_levels | Get observed water levels from a NOAA tide station as a time series. Choose the interval: "6" = standard 6-minute observations (preliminary or verified, max 31 days per request), "1" = 1-minute preli | typed |
noaa_get_water_level_summaries | Get verified summary water-level products from a NOAA station: - high_low: each day's observed highs/lows with ty = HH (higher high), H, L, LL (lower low). Max 1 year per request. - daily_mean: daily | typed |
noaa_get_tide_predictions | Get NOAA harmonic tide predictions (future or past) for a station. interval="hilo" (recommended for "when is high/low tide") returns the daily tide events with type H/L — up to 10 years per request. | typed |
noaa_get_currents | Get observed current speed and direction from a NOAA current meter station. Current stations use alphanumeric IDs (e.g. "cb0102" Chesapeake, "bh0101" Boston Harbor) — NOT the 7-digit water-level stat | typed |
noaa_get_current_predictions | Get predicted tidal currents for a NOAA current prediction station. interval="max_slack" (recommended for navigation) returns the tidal-current events — maximum flood, maximum ebb, and slack water ti | typed |
noaa_get_meteorological_data | Get observed meteorological/oceanographic sensor data from a NOAA station. Products: air_temperature, water_temperature, wind (speed/gust/direction), air_pressure, air_gap (bridge clearance to water | typed |
noaa_search_stations | Search the NOAA CO-OPS station directory by capability type, name, and/or state. Filter with: - type: what the station does (waterlevels, tidepredictions, currents, currentpredictions, met, ...) — pi | typed |
noaa_find_nearest_stations | Find the NOAA stations closest to a latitude/longitude point, sorted by distance. Use this to answer "what's the tide station near <place>?" — geocode the place to coordinates first, then call this. | typed |
noaa_get_station_info | Get a NOAA station's full metadata record: location, state, time zone, tide type, Great Lakes flag, capability flags, and links to available sub-resources. Optionally expand sub-resources inline via | typed |
noaa_get_station_datums | Get the accepted tidal datum values for a station: the elevations of MHHW, MHW, MTL, MSL, DTL, MLW, MLLW, STND, NAVD88 (where computed), plus GT (great diurnal range), MN (mean range), LAT/HAT (lowest | typed |
noaa_get_harmonic_constituents | Get the harmonic constituents NOAA uses to compute tide or current predictions at a station — the amplitude, phase, and angular speed of each tidal constituent (M2, S2, N2, K1, O1, ...). For water-le | typed |
noaa_get_prediction_offsets | Get the offsets a subordinate (type "S") prediction station applies to its reference station's predictions. kind "tide": returns refStationId, time offsets for high/low tide (minutes), height offsets | typed |
noaa_get_sea_level_trends | Get the long-term relative sea level trend at a NOAA station: trend and error (reported by NOAA in mm/yr or inches/decade — the payload's trendUnits field says which), the observation period (startDat | typed |
noaa_get_sea_level_rise_projections | Get NOAA's Interagency Sea Level Rise Scenario projections for a station (from the 2022 technical report): projected relative sea level (meters or feet, see units field) per decade through 2150 under | typed |
noaa_get_extreme_water_levels | Get NOAA's extreme water level exceedance statistics for a station: the annual exceedance probability levels (e.g. the 1%-annual-chance "100-year" level) and historical extreme events, computed from t | typed |
noaa_get_top_ten_water_levels | Get a station's highest recorded water levels: analysis "toptenwaterlevels" returns the ten highest events on record (with date, height, causal event name like "Great New England Hurricane", and categ | typed |
noaa_get_high_tide_flooding | Get NOAA high tide flooding (HTF, "nuisance"/"sunny day" flooding) statistics for a station. Reports: - daily: flood occurrence per day (REQUIRES start_date and end_date, YYYYMMDD) - monthly / season | typed |
astro_get_moon_phase | Get the moon phase for a date (or each day of a date range if end_date is given): phase name (New Moon, Waxing Crescent, ...), illuminated fraction, age in days within the 29.53-day cycle, distance (k | incomplete |
astro_get_next_moon_phase | Find the date(s) of the next occurrence(s) of a principal moon phase (New Moon, First Quarter, Full Moon, Last Quarter) from a starting date. Use for: "when is the next full moon?", planning around s | typed |
astro_get_sun_times | Get sunrise, sunset, solar noon, dawn/dusk (civil), nautical dawn/dusk, astronomical dawn/dusk, golden hour, and day length for a location and date (or each day of a range if end_date is given). Time | incomplete |
astro_get_sun_position | Get the sun's position for a date, time, and location: azimuth (degrees clockwise from north as rendered here), altitude above the horizon (degrees), plus approximate declination and right ascension. | typed |
astro_get_next_sun_event | Find the next occurrence(s) of a sun event (sunrise, sunset, dawn, dusk, solarNoon, night, nightEnd, goldenHourStart, goldenHourEnd, nauticalDawn, nauticalDusk, astronomicalDawn, astronomicalDusk) at | typed |
nws_get_wind_forecast | Get the NWS hourly wind FORECAST (speed, gust, direction — plus wave height where the grid carries it) for a latitude/longitude. Data comes from the NWS forecast grid (api.weather.gov gridpoints — nu | typed |
nws_get_marine_forecast | Get the official NWS Coastal Waters Forecast (CWF) narrative for the marine zone covering a latitude/longitude — day-part wind/seas text ("SE winds 10 to 15 kt... Bay waters choppy"), including Small | typed |
noaa_get_reference_guide | Get curated reference documentation for NOAA CO-OPS concepts and parameters. Topics: - products: Every NOAA CO-OPS data product and which tool serves it - datums: Vertical datums (MLLW, MSL, IGLD...) | typed |
