Relatively drier periods are generally preferred for extended trekking because trails can be easier to negotiate.
However, the Rwenzoris are famously wet, and rainfall or mist can occur even during months commonly described as drier.
This means waterproof clothing and reliable footwear are essential throughout the year.
Travelers attempting higher elevations should also prepare for dramatic temperature changes.
Warm conditions at lower altitude can give way to very cold mountain weather.
