Weather forecasts by satellite text

Text a weather question to 86-GETRELAY (+1 (864) 387-3529) from any satellite messenger and a live forecast comes back in one SMS — pulled from the same sources a meteorologist would check, compressed to 160 characters.

Land forecasts, anywhere

US locations get National Weather Service forecasts; everywhere else on earth falls back automatically to the Open-Meteo global model. Ask for tonight, a specific day, or the multi-day picture:

Weather this weekend at Desolation Wilderness?
Sat: sunny 68F. Sun: 71F, wind SW 10. No precip either day. src: NWS
Forecast at Chamonix tomorrow
Tmrw: Mostly clear, 62F high, light WNW wind. src: Open-Meteo

The reply always names its source — src: NWS or src: Open-Meteo — so you know exactly what you're trusting.

Marine: forecast AND ground truth

Two different questions deserve two different answers. The forecast comes from the global wave model; right now comes from a real NOAA buoy:

Swell forecast for Monterey Bay tomorrow
Waves 4ft @ 12s, swell 3.7ft @ 10s. Winds WSW 2mph, easing overnight. src: Open-Meteo
Actual wave height right now off Half Moon Bay? @37.46,-122.50
4.6 ft waves (6s period). NW wind 16 mph, gusts 20. Water 60F. src: NDBC

Tides come from the nearest NOAA station in station-local time, covering the next three days — so “tides tomorrow” just works.

Tides at Drakes Bay tomorrow
Aug 26: Low 04:47 -0.1ft, High 11:25 4.6ft, Low 16:22 2.7ft, High 22:19 6.0ft. src: NOAA

Mountain-specific: snow, avalanche, smoke

Snow depth @39.19,-120.24?
No snow on ground at nearby SNOTEL stations. src: SNOTEL
Avalanche danger near Mammoth Lakes?
Eastside Region: no active rating (off-season). Eastern Sierra Avalanche Center. src: avalanche.org
Air quality for my run tomorrow @44.06,-121.31?
AQI 59 max next 24h (Moderate). Acceptable for most; sensitive groups take it easy. src: Open-Meteo

Snow depth is measured — from the nearest SNOTEL stations, with distance and elevation considered. Avalanche danger comes from the official avalanche center for your exact zone, never from a web search.

Alerts and honest limits

Ask about warnings directly (“any alerts near me?”) and active red-flag, flood, storm, or winter warnings come back. And when a data source genuinely has nothing — tides at an inland lake, a buoy 300 miles from anywhere — Relay says so instead of guessing. A confident wrong answer in the backcountry is worse than no answer; the system is built to never send one.
