Mexico City and Tulum
The verdict for May
Great weather, no crush
+Great weather without the April crush, plus the low-key Feria de las Culturas Amigas.
–Rainy season is building — afternoon showers can start by month's end.
April's weather without April's crowds and prices.
Hot weather, fewer crowds
+Fewer visitors
–Increasing humidity
May is hot and increasingly humid, while rainfall starts to become more noticeable. Visitor numbers generally ease compared with the main high season, creating a useful balance for travelers seeking better value.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
