Holiday in Colombia or Argentina in August?

r/

I am planning a month long trip for August 2026 and I would like to get opinions on the most suitable destination with regards weather.

It would be a one month trip with a small child. We would move around every 3/4 days to see as much as possible. We aren’t the flop on a beach type so it would be mostly activities and exploring cities.

I am not concerned with the cold in southern Argentina but I would like some sun/warmth at some point during the 4 weeks.

So my question is whether I can get that sun in the North/up in Paraguay or whether actually the cold in Patagonia will make it far less enjoyable and I should head to Colombia instead.

Coming from Europe, I have contemplated 2 weeks in each Colombia and Argentina too – it wouldn’t be out of the way.
