HarborCast: Radar & Lightning

Live Weather & Forecasts

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Track lightning in real time, get alerts before strikes reach you, and read live marine radar, tides, PLUS custom conditions for your exact location. Customize weather your way! Radar, Lightning, Beach, Marine, and real conditions! Add your own weather ratings based on YOUR thresholds. See every lightning strike live on a beautiful radar map, and get warned before the storm reaches you. LIGHTNING, LIVE ON THE MAP Satellite-detected lightning strikes appear right on the radar, color-coded by age (bright red for the newest, yellow as they get older), with distance rings around you and a readout that always shows the nearest strike ("within ~10 mi"). Pro members get proximity push alerts with quiet hours, delivered even when the app is closed, so your phone warns you before you hear thunder. Set your alert distance anywhere from 1 to 30 miles with a simple slider. Free users can tap the lightning layer for a short live preview of real strikes. Lightning detection comes from the NOAA GOES satellite network covering the Americas. Distances are approximate. For awareness only: not a substitute for official warnings. RADAR THAT LOOKS THE PART A high-contrast storm map built for one job: showing you the weather. - High-resolution US NEXRAD radar as smooth, vivid color at every zoom - Satellite precipitation worldwide - Satellite clouds, day and night, across the globe - Scrub two hours of history with your finger, with real clock times on every frame - Opacity controls for every layer All of it free, for every user, forever. No ads. Ever. THE RATING THAT KNOWS YOUR LIMITS HarborCast turns NOAA data into one clear answer: Good, Poor, or Dangerous, hour by hour.
