CragReport vs Going Blue

CragReport gives you detailed weather conditions for thousands of crags worldwide. It pairs a physics-based thermal and drying model with hour-by-hour weather so you know when conditions hit their peak. Save your favorite areas, get notified when the conditions are good, and read what other climbers found on the ground. Features Conditions Score See a quality score for the current hour and every hour ahead. Tap any score for the top reasons driving it: rock temperature, humidity, dew point, sun, and wind. Five-Day Hourly Forecast See the forecast for any crag, with temperature, wind, precipitation, and condition rating per hour. Quickly find the best window across the week at a glance. Wall Configuration Get more accurate predictions for the wall you are climbing: Set wall direction (N–NW), overhang angle from vertical to 45°, and rock type — granite, sandstone, limestone, volcanic, gneiss, or quartzite. Wall conditions update based on these values to give you detailed insight on when it's the best time to climb. Rock-Aware Drying A two-phase drying model tracks surface film and internal moisture separately, so porous sandstone gets the patience it deserves and granite dries on its own clock. Past precipitation comes from NOAA MRMS radar, not just point forecasts. Map and Nearby Open a map of your saved crags and the closest crags around your current location. Tap any pin to jump straight to its forecast. Search by name or by location to find new areas. Push Alerts Get notified when a crag's conditions look good. Community Reports Read condition reports from climbers who were just there, with photos and notes on what the rock actually felt like. Submit your own report in seconds after a session.

Going Blue is an expedition weather app designed specifically for low-bandwidth satellite connections. It is built for skiers, alpinists, backpackers, kayakers, sailors, hunters, and anyone else who needs detailed weather forecasts in remote places. Going Blue works with direct-to-cell satellite internet, SMS, Garmin inReach, iPhone satellite messaging, and ZOLEO. How it works 1. Build a forecast request in the app. Choose the location, model, and variables that you care about. 2. Send the forecast request to Going Blue via the internet, SMS, Garmin inReach, ZOLEO, or iPhone satellite messaging. 3. Receive an encoded message from Going Blue. Paste it into the app to see a detailed forecast. Features - Satellite ready: Get forecasts anywhere in the world, without cell reception. Works with direct-to-cell satellite internet (Starlink Direct to Cell, T-Satellite), Garmin inReach, ZOLEO, and iPhone satellite messaging. - Hundreds of data points per message: Uses custom compression optimized for weather data to fit a detailed weather forecast into a single message. - 30+ weather models: Forecasts from high-resolution models like HRRR (3km), HRDPS (2.5km), ICON-D2 (2km), and MET Norway (1km). Automatically chooses the best model for your location. - Detailed cloud cover: See up to 10 levels in the atmosphere to differentiate between high clouds, valley fog, and whiteout conditions. - Mountain forecasts: Pressure-level winds and freezing level for high-altitude mountaineering. - Air quality: Plan around wildfire smoke and other pollution with AQI forecasts. - Model agreement: See how well the forecast agrees with models from NOAA, ECMWF, ECCC, and DWD. - Avalanche forecasts: Full avalanche forecasts from Avalanche Canada. - Works offline: All forecasts are saved on your device for comparing multiple models and past forecasts while offline. - Private: Going Blue requires no account and does not store your name, email, or phone number.
