The perfect month is November, after the wet season (June to October) but before the peak tourist season. The big resorts are packed out in winter and parts of the south can get uncomfortably humid during mid summer. Generally, however, the climate is dictated more by the landscapes than the seasons, so year-round there’s always somewhere ripe to visit.
Literally dozens of major airlines including many American carriers fly direct to Mexico. British Airways fly direct from London Heathrow to Mexico City three times weekly. Thomsonfly goes to Cancun in Mexico for around £500 return from London — although the odd bargain can be found for £300-£450.
Mexico has a good network of well-equipped buses, but the distances can
be huge. In fact, they’re massive! Domestic flights are excellent value (sometimes within a few
dollars of the bus price) and well worth considering. The main domestic airlines are Taca and Copa.
Budget offers car hire from Mexico City from £13.50 a
day including unlimited mileage when prepaid online.
