Thanks mate, great weather chart.

To get a 5 day forcast before you leave for Rio go to - rainorshine.com - click on world wide cities in the top right hand corner then go to Rio - today calls for high of 86, low of 60 with heavy rains, the next 4 days high will be in middle 70`s lows in the 61,62 range with partly cloudy skies, sounds like pretty perfect temps. to me. (not to hot)

man can this place throw some rain...never have I seen so much rain for so long...rio knows how to bounce back tho..these proud people cleaning up the mess without skipping a beat...

We were staying in Jacarepagua and were in one of those little vans when all that rain hit the other week. Between the rivers for roads and the crazy driver, I was sure I was gonna die!
