Cancún & the Yucatán is in its storm season right now, June to November. Most trips are unaffected, but a storm reroutes flights and closes beaches at a day's notice — the packing consequence is a buffer day and a charged power bank, not different clothes.
Going in November
The Atlantic hurricane season officially runs from 1 June to 30 November, with most activity between mid-August and mid-October. Most trips are unaffected; the ones that are, are affected badly.
What this means for your bag
A buffer day, and your documents on your phone
Storms reroute and cancel flights at short notice. Leave a day between the trip and anything unmissable, and keep bookings and insurance available offline.

Power cuts follow storms. A charged bank keeps maps, bookings and your ability to call someone alive through one.

Phone, passport and camera in something sealed. A cheap roll-top bag also doubles as the wet-clothes bag on the way home.
See the Weather Protection packA packable rain shell
Not a winter coat — it stays warm through the rain. A light hooded shell that folds into its own pocket ends up in the day bag instead of the hotel room.
