I am currently in the throes of planning a last minute trip to EZE and environs-- to use some UA VDB credit- and have been looking into a 2 week trip to Buenos Aires, Salta and Mendoza. I checked weatherunderground and the historical waether seems to be good for that time of year- but others have said to avoid July and go in spring summer or fall. I have not been to SA except for Bolivia and have wanted to visit EZE- I presume the Bariloche area is not so conducive to a July visit- but what about Valdes peninsula for whale watching?
I guess I am really askingif this were to be my only ttrip to Argentina- should I wait until a winter or fall trip?

I appreciate your help- on the ground advice is always helpful.
