Best time to visit Tulum

Aim for December to April if you get the choice: humidity and rainfall are at their lowest, which is what actually varies here, and highs average 82°F (28°C) against roughly 12 wet days a month. For the same question asked the other way round, see where else is warm in December.

Pack for Tulum with light clothing for the warm months, proper waterproofs rather than an umbrella - wet days are the norm here and moisture-wicking fabrics for the humidity. Even in July, lows of 79°F (26°C) make an extra layer worth the space.
