Built for the backcountry
Built for alpine ascents, remote coastlines, and deep backcountry, BoltWX provides on-demand forecasts with the details that climbers, hikers, skiers, and paddlers need to stay safe far beyond cell signal, where only satellite messaging can reach.
The most reliable forecasts
BoltWX uses high-resolution forecasts from ECMWF, the US National Centers for Environmental Prediction (NCEP), and the Meteorological Service of Canada (MSC) to provide detailed and up-to-date weather for your specific location.
Activity focused
Get location-specific weather, avalanche bulletins, wildfire information, and coastal paddling conditions delivered directly via satellite to your iPhone, compatible Android phone, or satellite communicator.
Works with your phone or satellite device
No separate device required if your phone supports satellite messaging. Works seamlessly with Apple Satellite Messaging (iPhone 14 and newer) and satellite-capable Android devices (Google Pixel, Samsung Galaxy), as well as Garmin inReach®, ZOLEO™, and ACR Bivy Stick™.
