Everest Base Camp Trek is best done in the spring (March to May) or autumn (September to November). During these months, the weather is stable, the skies are clear, and the views are perfect. In spring, the hills are full of blooming rhododendrons. In autumn, the air is crisp and clean. Winter can be very cold, and summer brings rain and clouds. https://gloriousecotrek.com/trip/everest-base-camp-trek-in-nepal/
