"I feel, Rock climbing makes my core groups very strong. it adds wrist and forearm strength and stamina, and tones and streamlines from my shoulders to lower back. it even helps with balance and concentration ..."

And Rock climbing is good for your legs too.
It sounds like a very good way to keep in shape for golf. To exercise muscles it might be good to do it a little more often than oce a fortnight. Maybe 2 - 3 times a week.

About the weather - here in Jyväskylä, Finland - I will go skiing today. It's from - 10 to - 14 C today. A very nice weather for skiing.
