Skydiving planning tools
Weather Forecast Manual
The Weather Forecast tool displays meteorological forecast data over time in a single chart so skydivers can review trends across a planned jumping period.

Altitude note
AGL is true altitude above ground level. True AGL may not match barometric altitude because barometric instruments can read differently due to pressure setting, temperature, elevation reference, and atmospheric conditions. Treat altitude rows as forecast reference levels, not as a guaranteed match to a skydiving altimeter.
