I think you may have it backwards Bud: Generally, the hotter the climate the heavier the oil weight. I use 5w50 Synthetic Castrol in my 420 SEL here in south Georgia. In the Summer, the temps are high 90's. My car uses no oil at all with 125k on it. The few extra pennies are good insurace in my view.
