The link to Torey Pines Glider Port lil' weather station is on the LJ Webcam page.
Paragliding Club folks maintain it, and they need accurate readings - the wind can really impact their ability to play.
It is THE best place to see what the wind is doing at LJ - real time, plus recent data.
You can change the period to 4 hour, 1/2 day, 1 day, 2 days etc. to get an idea about the wind patterns.
