Best Times to Visit Tulum
The best time to visit Tulum is between October and December. You'll get the benefit of post hurricane-season breezes, plus the hotel prices are reasonable. Not to say that it's hard to find good room rates at other times of year -- this small pocket of the Yucatán has one of the widest ranges of price points on Mexico's Caribbean coast. If you're concerned about crowds, however, avoid the region from January to March.
* Weather for Cancun
There are deals to visit Tulum at this time, but you'll have to do a little digging. Temperatures rest somewhere between the high 60s and high 80s, and there's a slight chance of rain. But this is the peak season; the ruins and Sian Ka'an Biosphere Reserve will be jam-packed.
In late spring, the room prices fluctuate widely (they could be less than $100 or more than $400 a night) and the temperatures climb.
Tulum is heavy in the throes of hurricane season, and those hotels that are open are practically giving their rooms away. You'll have to weigh the unbelievable fares against the chance of a bad storm. Even if there isn't a hurricane, you can count on several rain days and sweltering temps.
Temperatures fall to around the low 80s as the hurricane season slides away. Plan a trip for the early part of this season if you want to save money. By early winter the stateside tourists have begun to arrive.
