In the months of November thru February you can find flights to Peru for as low as $451. The Summer season in Peru is December to April with the hottest months being December and January. The rainy season begins around January so if you are looking for a beach vacation, keep that in mind. A jumper flight to Cusco is only 1 1/2 hours if you plan to visit Machu Picchu. Definitely something on my bucket list!
