perigee_find_best_timeRank the best time windows over the next 1–7 days for a coastal activity — tidepooling, beachcombing, clamming, fishing, paddling (kayak, SUP), boating, photography, or a beach walk — from predicted tides, daylight, and forecast wind, with the reasons for each window. Use for "b…
perigee_find_stationsList NOAA tide stations by place or station name, by state, or nearest to a latitude and longitude. Use when a place is ambiguous, when someone asks which tide stations are near somewhere, or to compare candidate stations before choosing one. The other Perigee tools resolve plac…
noaa_get_water_levelsGet 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 preliminary data (max 4 days), "hourly" = verified hourly heights (max 1 year). Heigh…
noaa_get_water_level_summariesGet 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).

noaa_get_currentsGet 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 station IDs. Find them with noaa_search_stations (type "currents") or noaa_find_near…
noaa_get_current_predictionsGet 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 times — up to 1 year per request. Other intervals (h, 1, 6, 10, 30, 60 minutes) re…
noaa_get_meteorological_dataGet observed meteorological/oceanographic sensor data from a NOAA station.

noaa_search_stationsSearch 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, ...) — pick the type matching the data you plan to request. - name: case-insensitive subs…
noaa_find_nearest_stationsFind 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. Filter by type to match the data you need (e.g. type "tidepredictions" before ca…
noaa_get_station_infoGet 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 the "expand" list: - details (established/removed dates), sensors (installed ins…
noaa_get_station_datumsGet 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/highest astronomical tide), and the station's historical extreme min/max water…
noaa_get_harmonic_constituentsGet 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-level stations: amplitude (feet/meters), phase_GMT and phase_local (degrees), spee…
noaa_get_prediction_offsetsGet 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 for high/low tide, and whether the height adjustment is a ratio (multiplied) or…
noaa_get_sea_level_trendsGet 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 (startDate/endDate), and seasonal amplitude. Relative sea level combines ocean rise AND…
