Mount Aconcagua in Argentina is a wonderful mountain to attempt in January — there are shorter one and three-day treks, but if you plan to summit the mountain, allow for about three weeks. Alternatively, January in Mount Kenya is one of the driest in the area, making sure you won't slip or fall on slick mud or have to climb icy rocks.

February is generally dry in South America, and Antisana, one of Ecuador's highest peaks, has amazing views but should be attempted by only the most experienced climbers, or those with very good guides. This is also the most ideal time to tackle Africa's most famous peak, Mount Kilimanjaro, due to the good visibility and dry weather.

Stick to the southern hemisphere in March, for peaks like Ojos del Salado, which spans Chile and Argentina, with pre-booked huts, jeep ride options, and the least strenuous hike up. If you prefer pre-monsoon climbs, start on the world's most famous mountain, Mount Everest — despite the frigid temps — as there are fewer crowds, and crisper views.

In the northern hemisphere, there is still some snow on the ground in many locations in April, making for nice winter adventures without freezing temps, like in the Canadian Rockies. Pre-monsoon season begins on Mount Everest, but it's a bit warmer, which brings more people and higher prices for amenities and supplies.

May is a fantastic mountaineering month, as options open across the globe, including the Central European Alps (stretching from France to Italy to Slovenia), the Cascade Range, and Mount Rainier in Washington state. Morocco's highest peaks have the most favorable conditions, as does the Inca Trail in Peru.
