PocketGrib vs Actual Currents

With PocketGrib you can download, view and analyse global weather data while on the go. Wind, precipitation, pressure, temperature, wave and other data extracted from GRIB files are displayed through our powerful GRIB viewer interface. Perfect for sailors (both sailing and in the pub), windsurfers, storm chasers, outdoor enthusiasts, amateur and professional meteorologists. Features - Choose your map location and have weather information overlaid - Animation of weather maps - Weather can be viewed as a meteogram (graph) or raw data - Configurable download to minimise file sizes (great for roaming) - GRIB files can be downloaded to your PC via iTunes - Displays online and offline - Support for 3rd party GRIB files PocketGrib downloads and displays the following weather types: - Wind speed and direction (10 m above ground/sea) - Precipitation (rain, snow etc) - Pressure - Air temperature - Waves (including Mediterranean and Black Sea) - Cloud cover - Relative humidity - CAPE (Convective Atmospheric Potential Energy) - Current (Atlantic only) - 500mb Height Direct download of GRIB data from NOAA's GFS (Global Forecast System) model - Forecasts up to 8 days - Data steps: 3hr, 6hr, 12hr - Worldwide coverage - Resolution: 0.25°, 0.5°, 1°, 2° - Data updated 4 times a day (every 6 hours) Also support for COAMPS (0.2° resolution), WW3, NOGAPS, RTOFS (Currents) and FNMOC WW3 (Mediterranean wave) models. GRIB forecasts are published without human intervention or review. As such, the end user requires some knowledge and awareness. Most GRIB models do NOT accurately forecast hurricanes and tropical cyclones so their use should be combined with specific hurricane and tropical cyclone forecasts.

Actual Currents brings tidal currents to life with real-time animated particle visualization on a nautical-grade interactive map. See the actual flow of water in your area — not just tide times, but the speed and direction of tidal currents rendered as thousands of flowing particles over a detailed heatmap. Plan your trip with confidence by scrubbing through time to see how currents change throughout the day. FEATURES • Animated tidal current visualization with speed-colored particles and GPU-accelerated heatmap • Time scrubber — view current predictions for any time, past or future • Globe view with global ocean currents when zoomed out • Real-time wind overlay with global weather data • ENC nautical chart data with navigation aids, depth soundings, and depth contours • Satellite, bathymetry, and nautical basemap options • Route planning with current-aware analysis • Trip logging with GPS drift tracking • Location search to jump to any harbor or waterway COVERAGE • US Atlantic coast — Maine to Florida • US Pacific coast — Washington to California • Gulf of Mexico • Global ocean surface currents BUILT FOR BOATERS Whether you're sailing, fishing, kayaking, or navigating commercially, understanding tidal currents is critical for safety and efficiency. Actual Currents gives you an intuitive, visual understanding of water movement that tide tables alone can't provide.
