About
ParaglidingWX is a purpose-built weather forecasting web app designed exclusively for paragliding and free-flight pilots. Unlike generic weather services, it presents aviation-relevant atmospheric data through specialized tools including Windgrams, Skew-T diagrams, Thermal Maps, Wind Maps, Cloud Maps, Rain Maps, and Smoke Maps. Pilots can simulate Hike+Fly routes and use a built-in ruler and topographic overlays (TOPO, SAT) for pre-flight planning. The platform taps into multiple high-resolution numerical weather models — including HRDPS (~1 km and ~2.5 km resolution), GFS, HRRR, ICON, ERA5, and ECMWF — to generate detailed forecasts. It visualizes key parameters like parcel buoyancy (thermal strength), lapse rate (atmospheric stability), Lifting Condensation Level (cloud base), Boundary Layer height, surface solar radiation, and Deardorff convective velocity scale (w*). Colour-coded charts make it easy to assess whether thermals will fire, how high they will reach, and what stability conditions exist at each altitude. The platform also integrates experimental smoke/PM2.5 data via FireSmoke.ca for wildfire awareness. Airspace layers and KK7 Skyways overlays provide further situational awareness. ParaglidingWX is ideal for recreational paragliders, competition pilots, and adventure hikers planning Hike+Fly missions who need deep atmospheric insight beyond standard weather apps.
Key Features
- Multi-Model Weather Integration: Aggregates forecasts from HRDPS, GFS, HRRR, ICON, ERA5, and ECMWF to provide high-resolution, reliable atmospheric data for flight planning.
- Thermal & Lapse Rate Analysis: Visualizes parcel buoyancy and atmospheric lapse rates with colour-coded charts to show where and how strongly thermals will develop.
- Windgram & Skew-T Diagrams: Displays wind speed and direction by altitude alongside Skew-T log-P diagrams for professional-level atmospheric sounding analysis.
- Layered Map Views: Offers Wind, Thermal, Cloud, Rain, and Smoke maps with topographic (TOPO/SAT), airspace, and KK7 Skyways overlays for comprehensive situational awareness.
- Hike+Fly Route Simulation: Built-in Hike+Fly simulator with a ruler tool lets pilots plan multi-leg adventure flying routes with full terrain context.
Use Cases
- Pre-flight thermal forecasting for paragliding cross-country flights using multi-model wind and buoyancy data
- Planning Hike+Fly routes by combining topographic maps with atmospheric stability forecasts
- Assessing wildfire smoke impact on visibility and air quality along a planned flying corridor
- Competition paragliding task planning using high-resolution HRDPS wind and boundary layer forecasts
- Training and education on atmospheric science using Skew-T diagrams and lapse rate visualizations
Pros
- Highly Specialized for Free-Flight: Presents weather data in formats (Windgrams, Skew-T, thermal lift strips) that are directly meaningful to paragliding and hang gliding pilots.
- Multiple High-Resolution Models: Pulls from several NWP models including HRDPS at ~1 km resolution, giving pilots access to some of the finest-scale forecasts available.
- Free to Use: Accessible without any subscription or payment, making professional-grade atmospheric data available to all pilots.
Cons
- Steep Learning Curve: Skew-T diagrams, parcel buoyancy charts, and lapse rate visualizations require meteorological knowledge to interpret correctly.
- Limited to Paragliding Use Case: The highly specialized nature means it is not useful for general aviation or non-flying outdoor activities.
- Experimental Features: Some features like the smoke/PM2.5 layer are experimental and explicitly not recommended for emergency use, limiting reliability in critical situations.
Frequently Asked Questions
What weather models does ParaglidingWX use?
ParaglidingWX integrates multiple models including HRDPS (~1 km and ~2.5 km), GFS, HRRR, ICON, ERA5-based runs, and ECMWF, allowing pilots to compare forecasts from different sources.
What is the Windgram and how do I read it?
The Windgram is the main chart showing wind speed and direction by altitude over time. Below the wind data are Solar and Lift strips that indicate surface heating strength and estimated thermal updraft intensity in m/s.
What does the Parcel Buoyancy chart show?
It shows how buoyant a surface air parcel would be at each altitude, using colour coding: warm colours indicate the thermal is still rising, cool colours indicate it has been capped by a stable layer.
Is ParaglidingWX free to use?
Yes, ParaglidingWX is free to access via the web with no subscription required.
What is the Hike+Fly Sim feature?
The Hike+Fly Sim lets pilots simulate multi-leg routes combining hiking and flying segments, helping plan adventure flying trips with terrain and weather context.
