I seldom do predictions as doing so is outside the 5 minutes at a time way I live. Having said that, just for fun (like guess the rain) I am guessing that the peso will weaken just in time for tourist season and may be at 18 by the end of next week.

I searched - what are the odds that the usd peso exchange rate will rise to 19 for Mexico's tourist season -. I didn't find much to support my hunch

other than this, which says 18 by December 19 by April.
