Weather
Be aware that the weather can suddenly change at Le Touquet.
I left a beautiful cloudless sky over London on Bastille day and by the time I was mid channel Le Touquet was closed VFR and was directed to Calais radar. Convinced them to let me do an instrument let down and broke out at 200ft.
A few years later I delivered a gin Palace into the canal network crossing from the Goodwins to Cape Gris Nez and was enveloped in thick fog mid channel although none forecast.
have fun
