SkySight
SkySight is an interactive forecasting tool. It combines the latest forecast modelling technologies with an intuitive user interface, to provide high resolution forecasts and powerful flight planning tools. Access is provided to all available regions and forecasting tools with a single subscription. A 12 month subscription costs 79 US dollar which currently equals about 70 euro.
SPECIAL OFFER: order 13 months for the price of 12 using code GPS4U or via this direct link: |

The software is browser based, therefore you will always be using the latest version. Please ensure that your browser is up to date to ensure the best compatibility. For LXNAV and SeeYou SkySight users, updates are integrated within the regular device firmware and software updates |
 |
 |
SkySight will work with all modern browsers, on all platforms. Chrome is recommended for the best compatibility. The website is designed to work on all screen sizes, although some advanced features require larger screen sizes. For mobile devices, SkySight is accessed via the browser and dedicated mobile website. |
|
SeeYou PC can connect with SkySight to provide forecast overlays on the native maps. This feature is available from SeeYou PC V8.0 onwards and can be used for task planning and post flight analysis. |
 |
 |
SkySight forecast overlays are available to LXNAV users who use the LX80xx and LX90xx series flight computers. The WiFi module must be installed and software updated to the latest version. |
|
SkySight can also be displayed on Oudies with the latest software version. Simply connect the Oudie to a PC with the program SeeYou and run Naviter Updater to upload the weather maps to your Oudie. |
 |
| Weather data can be displayed for a certain location or for an entire regions (South Africa, Europe, Italy, US West, Canada, Mid US, US East, Eastern Canada, Spain, Morocco, Argentina, New Zealand, Brazil, Japan, Andes, West Australia, East Australia). |

Overiew of forecast maps available in SkySight:
| Potential Flight Distance | Distance an 18m- or Club-class glider might be expected to fly, taking off at first thermals and landing at last, assuming MacCready theory in high conditions and slower in weak |
| Cross-country Speed | XC Speed an 18m-class glider might be expected to fly, in an hour, according to MacCready |
| Thermal Strength & B/S Ratio | Strength of thermals, with an indication for how broken the thermals will be (Buoyancy Shear ratio) |
| Height of Thermals | Height at which thermals fall below 0.9 m/s |
| Depth of Thermals | Height above ground at which thermals fall below 0.9 m/s |
| Surface Heating | Heat transferred into the atmosphere due to solar heating of the ground, creating thermals |
| Cu Depth | Difference between the top of predicted thermals and the condensation layer, increasingly positive values indicating more likely cumulus, negative values indicating unlikely cumulus |
| Cu Cloudbase | In areas where cumulus is expected to form, the height of that cumulus above sea level |
| Overdevelopment | Shows areas likely to overdevelop, as a percentage of 600 m depth of overdevelopment |
| CAPE / Storms | Convective Available Potential Energy. Higher values indicate greater potential instability, larger updraft velocities within deep convective clouds, and greater potential for thunderstorm development |
| Rain | Rain accumulated over the last half hour |
| Low level cloud cover | Low cloud cover percentage, of any type, eg. Cu, Sc, St (1013 hPa - 642 hPa, 0 - 4000 m, 0 - FL 130) |
| Mid level cloud cover | Mid level cover cloud percentage, eg. Ac, As, Cb (642 hPa - 350 hPa, 4000 - 10000 m, FL 130 - FL 330) |
| High level cloud cover | High cloud cover percentage, eg. Ci, Cs (350 hPa - 150 hPa, 10000 m - 20000 m, FL 330 - FL 650) |
| Forecast Satellite View | Cloud cover forecast intended to mimic a real satellite photo |
| Surface Temperature | The temperature at a height of 2 m above ground level |
| Surface Dewpoint | The dew point temperature at a height of 2m above ground level |
| Synoptic Map | Analysis chart from the UK MetOffice |
| Ridge Lift | Areas of predicted ridge lift...duh |
| MSL Pressure | Atmospheric Pressure at Mean Sea Level in mBar |
| Surface Wind | The speed and direction of the wind at 2 m above the ground |
| Boundary Layer Wind Average | The speed and direction of the vector-averaged wind in the Boundary Layer |
| Boundary Layer Top Wind | The speed and direction of the wind at the top of the Boundary Layer |
| Wind Shear | Difference in wind between the top and bottom of the Boundary Layer |
| Wave Cross-section | Customizable cross-section of wave activity |
| Convergence | Maximum up/down motion within the Boundary Layer, as created by horizontal wind movement |
| Vertical Velocity | Vertical velocity at 600/1500/3000/4000/5000 m (950/850/700/600/500 mBar), plus wind speed/direction barbs Used for wave/convergence |
| 3D Wave | Three dimensional display of wave activity |
| Significant Weather | Significant weather overlaid on height of thermals |
| Freezing Level | ...brrrrrrr... |
| Turbulence | Absolute Changes in Vertical Velocity |
