Semana Santa (Holy Week) often occurs in late March or April and is the primary event that affects April travel between James M. Cox Dayton International Airport (DAY) and Manuel Crescencio Rejón International Airport (MID). During Semana Santa, Mérida and nearby beach towns like Progreso see increased domestic tourism, higher hotel rates and fuller flights — plan and book well in advance. Aside from Holy Week, Mérida hosts cultural performances, folkloric events along Paseo de Montejo and artisan markets that spring up in April, ideal for travelers seeking authentic Yucatán experiences. In Dayton, April brings spring festivals and outdoor markets that can influence regional travel patterns. CTA: If your April travel overlaps with Semana Santa, reserve flights and accommodation now to avoid surges in price and limited availability.
