Weather - South Downs Hang Gliding


Wind Speed & Direction

Light winds with good lift provide the best flying conditions. Winds in excess of 20mph can be unpleasant. The wind direction determines which flying sites we will visit on the day.

The South Downs are perfect for learning to fly hang gliders. We have training slopes facing all wind directions and roads to the top for the higher launches. Our south coast climate provides far more good flying days than other areas. More pilots have learnt to fly here than anywhere else in the UK.

The wind speed and direction, and any "significant" weather can be read from surface pressure charts. This actual chart (nowcast) has the isobars shown for each millibar. (Image from "Meteorologica")

These days the forecasts are very accurate for the next day then gradually decline in reliability over the following days. Beyond five days the weather system is considered too unpredictable for useful forecasts.
Notes on meteorology


Training Weather

Introductory Days One and Two are flown in a wide range of conditions using our tether rope systems. The low solo flights of EP and CP courses require light winds to avoid turbulence. For the high flights at the end of the CP course we need light winds with a northerly component. Try watching the five day forecast, (link below), to spot the days with light winds. Call us to get your name in the diary!
Our famous southerly sea cliffs are not used for solo training flights!
