    Weather trends in Merida

    Here are four points to keep in mind about the Yucatan's weather:

  • it's warm year-round
  • there are marked dry and wet seasons
  • on the average, it's an arid climate
  • hurricanes occur in late summer and fall

    • In general the dry season lasts from November through April and the wet season lasts from May through October. However, sometimes the seasons come late or early, or are not as distinct from one another as they usually are.

    Hurricanes are important because they can destroy vast expanses of forest and flood large parts of the interior with saltwater. During the dry season, fires burn large areas, too. Between the hurricanes, fires and human disruption, much of the Yucatan's natural history is disturbed, threatened or destroyed.
