Weather Signal: Outdoor Safety

Weather Signal gives you a plain-English answer to the question you ask every morning: is it safe to go outside? Instead of handing you raw numbers and leaving you to guess, Weather Signal reads air quality, wildfire activity, pollen levels, marine conditions, and weather — then gives you a single clear signal: Go, Caution, or Avoid. WHAT WEATHER SIGNAL MONITORS - Air Quality — Real-time AQI from EPA AirNow sensors near you, with plain-English health guidance - Wildfire & Smoke — Active fire proximity and wind-driven smoke movement from NASA satellite data - Pollen — Daily tree, grass, and weed pollen levels so allergy sufferers can plan ahead - Marine & Water Conditions — Wave height, tide predictions, and coastal safety indicators - Weather — Current conditions, severe weather alerts, and a 10-day forecast ONE SIGNAL. CLEAR GUIDANCE. Every data source feeds a composite safety engine that weighs conditions together and produces a single recommendation. No translating numbers. No toggling between apps. Just an answer. SMART NOTIFICATIONS Weather Signal monitors conditions in the background and alerts you when something changes — an AQI spike, a new severe weather alert, or wildfire activity approaching your area. Notifications are filtered intelligently so you only hear from the app when it matters. BUILT FOR PEOPLE WHO GO OUTSIDE Runners, cyclists, hikers, parents, people with asthma or allergies, coastal residents, and anyone who spends meaningful time outdoors. Weather Signal is designed for people who actually need to act on this information — not just read it. DATA SOURCES - Air quality: U.S. EPA AirNow - Wildfire: NASA FIRMS satellite fire detection - Weather & severe alerts: Apple WeatherKit + NOAA/NWS - Pollen: Google Pollen API - Marine: NOAA CO-OPS tides and Open-Meteo wave data Weather Signal provides environmental information for general awareness purposes. It is not a substitute for official emergency guidance. Always follow instructions from local authorities during emergencies.
