Not necessarily. It's possible to make a high camp at about 4,900 meters, shortly before the base of the Jamapa glacier. In fact, making a double carry to this camp from base camp is a good way to acclimate, and the campsite itself is in a spectacular setting. We did exactly that during our ascent in 2005 and it was worth it IMO.[/quote]

Again, not necessarily true. What is
true is that the Mexican volcanoes are typically climbed during the dry season (Dec-Feb), and the dry-wet season does seem to be more pronounced in southern Mexico than the Cascades, so yes, statistically you are less likely to encounter avalanche conditions simply because there is less probability of recent snowfall. However, if it happens to snow the day before your ascent (which it can, and has, even during the dry season) , the summit cone of Orizaba will be as avalanche-prone than any of the Rainier routes;it's a 2000-foot, 35-45 degree, wide open snow slope, which is pretty much ideal avalanche terrain.
I wouldn't worry too much about this, though if you are with a guided group - I doubt they will take you up if there's even a chance of avy danger on the route...
