Hello everyone, Me and my friends are planning to cycle from Amsterdam to Paris in 24 hours. Since it's a 500km ride, we need the best circumstances, most importantly the winds at our backs. I know there are trends for wind direction. Can anyone help me decide whether we stand the best chance in summer or spring to have a Northern, North Eastern wind? Thank you for giving a push in the right direction! Xander
