Getting into super cold water?

We live in a valley and we like going swimming in the mountains. Where I'm at the air with no wind feels like 110-115 degrees sometimes and I love jumping in 40 degree water (sometimes it's about in the 50s) but I was wondering could this hurt my baby just as much as hot water? I feel fine in the water and when I get to cold I obviously get out. I'm almost 9 weeks.
