May is part of the variable short-rain season; in some years showers are frequent and in others they are light. Travelers should plan flexibly for potential wet weather in highland areas.
May often marks the start of sustained wet weather in the northern highlands as Belg gives way to stronger rains; the Simien massif and areas around Lalibela see increasingly frequent afternoon showers. Rose-tinted mornings can turn to dramatic cloud buildups; trekking becomes greener but slipperier, and some remote tracks may be impassable. Expect fewer tourists, lower prices, and bring good hiking boots and a rain cover for packs; river crossings may rise suddenly.
Central Highlands & Rift Escarpment
Addis Ababa, Debre Birhan, Adama, Awash
May marks the increasing influence of Belg with intermittent rains making the countryside around Adama and the Rift rim greener and cooler at times, though heavy downpours remain mostly to the north and west. Road conditions can vary quickly after sudden storms; check with drivers about minor washouts. City-based travel (Addis) is still convenient and pleasant - bring waterproof footwear for brief muddy patches.
Bale Mountains & Southeastern Highlands
Bale, Sidamo, Yirgacheffe, Harenna Forest
May sees the southeastern highlands becoming distinctly greener as the Belg continues, feeding coffee plantations and raising humidity in the valle ys around Sidamo and Arba Minch. The Bale massif can experience afternoon storms that make high plateau camping damp; valleys hold more insect life, so bring repellent for lower-elevation forest treks. Cultural experiences around coffee production are rewarding now, though some routes may require 4x4 vehicles.
Southern Highlands & Omo Valley
Arba Minch, Jinka, Konso, Omo River
May often brings steady, sometimes heavy showers through the southern lowlands which green the plains and boost river flows - the landscape becomes intensely fertile and dramatic. Visiting conditions are wetter and some village visits require waterproof boots and patient local drivers. Cultural visits continue but logistical delays are common; ensure flexible bookings and mosquito protection due to increased malaria risk in low elevations.
Eastern Lowlands & Afar/Danakil
Afar Depression, Danakil Depression, Mille, Dire Dawa, Somali border
May pushes toward the year’s peak heat in the Afar Depression and Somali lowlands; salt flats and volcanic terrain are intensely hot and travel becomes more taxing - plan short, early starts and long afternoon rests. Local guides will often limit time near fissures like the Dallol terraces during midday for safety. Hydration strategy, shaded camps and a strong physical condition are essential for any lowland excursion.
Western Lowlands & Gambela
Gambela, Benishangul-Gumuz, Metekel, Blue Nile headwaters
May marks the start of more consistent rainfall and rising river levels in Gambela and Benishangul-Gumuz: expect frequent afternoon downpours and saturated ground that can slow drives to remote villages. Boat navigation may become trickier with runoff and fallen trees; some seasonal camps close for safety. Rain gear, goodwet-weather footwear and flexible schedules are essential if you travel now, though the forest life is at its most active.
