There are many factors to consider when deciding when to go to Cabo San Lucas. The most important factor is the weather, but there are other things that you should take into account as well. If you want a beach vacation in Mexico then make sure that your dates fall between late December and mid-February (preferably February). That’s because this is when the beaches in Cabo San Lucas tend to be at their best condition for swimming and sunbathing. But if you have some flexibility with dates then it could even be better, especially if the weather looks good or if you can get really cheap flights or hotel deals during these months. Either way, booking around this time frame will guarantee that whatever accommodation plan suits your needs are available on what turns out to be one of Mexico’s finest destinations near Baja California Norte!
