Mexico's wonderfully diverse topography includes everything from tropical coastlines to barren deserts, frosty mountain peaks to lush valleys. Needless to say, the country's weather is incredibly varied and as affected by altitude as it is by longitude.
That said, the general climate in Mexico is warm-temperate, and most of the country experiences year-round sunny weather. In places with higher altitude – Mexico City included – expats may experience shortness of breath until they adjust to the change in pressure. These locales can experience extremely hot temperatures during the day with sudden shifts resulting in cold evenings.
Mexican coastlines are known for their high temperatures, averaging between 89.6°F (32°C) and 95°F (35°C) throughout the year, and their moderate-to-high level of rainfall. Occasional tropical storms between August to September have been known to bring heavy rains.
Otherwise, precipitation in Mexico is most common between June and November; the remaining months of the year are relatively dry. This feature serves to separate seasons in Mexico more so than temperature difference.
Expats concerned about the weather in Mexico should research the specific region they'll be moving to for more information on what to expect.
