That is the altitude of Queretaro! This is what gives us the cool nights that make it so east to sleep. Temperatures for this week will be +/- 25C (77F) in the daytime and +/- 10C (50F) at night. Perfect weather and similar to our summers at home.
You do notice this altitude when walking. I thought it was my age but I think it is the rarefied oxygen at this altitude. I am getting used to it now but I found myself slightly out of breath after a long walk or serious activity when we first arrived. Now, I am actually quite comfortable living at this altitude and I am sure it is good for me.
It is also noticeable when drinking coffee. Water boils at a lower temperature up here so coffee is not as hot as it is at sea level and cools down quickly. For someone who loves hot coffee this is a great inconvenience :).
