Im going down on Feb 29 to sobo the BMT from Fontana to Springer and have been watching the 10 day for Robbinsvile area as of now feb 18 to 21 looks like highs in the 60s and lows at night in 30s. In 2000 I woke up in Betty Gap to 15 degrees in March, thats when I learned to keep my water and filter in tent. Ill be prepared either way.
