Weather at end of Dec.
 

Hello!
My husband and I are finally heading off to our honeymoon in Argentina in a few weeks!! I was wondering what the weather will be like in the various places we will be in: Mendoza, Bariloche, Buenos Aires, and Iguazu.
I figure it will be fairly hot but I wanted some more details, and does it get cool at night in any of those places?
Thanks..and I"m sure I"ll be back with more questions...

In Bariloche, it should get cool at night.

Have a wonderful honeymoon with your hubby in our country, sharbear84!

In Salta also gets cool at night! Much cooler than in BA.
LOL! But this is serious. It is true.

Congrats on the marriage! In Bariloche, you can expect highs in the 60's and 70's and lows in the 40's and 50's, and sunsets around 9:30-10pm.

That sounds wonderful - glad we will have a break from the heat somewhere. And I had no idea the sun sets so late!
Thanks for all the well wishes.
Will it be super hot in BA, Mendoza, and Iguazu? I'm pretty sure the answer to that is yes but wanted to be sure...are we talking highs in the 90s?? or not that hot...

It will be HOT in Mendoza, BA and Igauzu by the time you get here. It's already hot here in BA - expected to reach 95F today. Iguazu and BA will be very humid. Mendoza will be very hot but very dry, making the heat a bit more tolerable perhaps.
