Météo à Addis-Abeba en septembre

Forum posters describe July as squarely within Addis Ababa's rainy season (typically running June through September), with rain possible any time of day - some days bringing thunderstorms, others lighter, longer showers - but rarely lasting the entire day. Posters are consistent that the rain shouldn't disrupt a well-planned trip, recommending a waterproof jacket and decent walking boots for the muddy aftermath of a downpour. Posters note the rains bring a real upside too: lusher landscapes and noticeably fewer tourists than the dry-season peak. Posters do flag genuine regional variation - rainfall is much lighter in lowland areas south of Addis, and the far-south Omo Valley isn't in rainy season at all this time of year. Posters generally rate July as wet but manageable for Addis Ababa itself, warm days with a real chill still possible after dark.

Forum posters describe August as squarely within Ethiopia's rainy season, with Addis Ababa and the central highlands seeing rain virtually every day - sometimes heavy tropical downpours, other times more like a persistent UK-style drizzle. Posters describe the pattern as genuinely unpredictable within a single day, sunny one minute and pouring the next, with conditions overall cold, wet and cloudy for long stretches. Posters are consistent that this shouldn't rule out an August visit, though: most tourist roads, especially in the north, are properly paved and stay accessible, and posters flag the real upside of fewer crowds during this off-season stretch. Posters consistently recommend a proper rain jacket and boots as essential packing for an August trip to Addis Ababa.

Addis Ababa forum regulars describe January as hot by day and genuinely cold by night — the altitude, roughly 8,000 feet, doing the work: “daytime temperatures...reach around 28°C at lunchtime and 4°C at 3am,” with a jumper or track top needed “from 5pm onwards” even though the afternoon felt like shorts weather. Rain is essentially off the table — deep in the dry season, “highly unlikely significant rain.” January is also called out as the best month to catch Ethiopia's Timkat (Epiphany) celebration on the 26th-27th, alongside Ethiopian Christmas on the 8th — genuine cultural draws layered onto the dry-season weather. Our record: 22.7°C days, 8.6°C nights and just 0.8 rain days for the month — dry as described, with a day-to-night swing wide enough that the forum's “jumper by evening” advice tracks.

February sits in Addis Ababa's dry season — October to May, with hardly any rain at all from October through February — and January to February is Ethiopia's high season. The number that matters here is not the daily high of about 24°C but the spread: the city sits at 2,750m, so temperatures barely move across the year while the gap between day and night is large. Regulars say it drops away quickly after 5pm and you will want a jumper or a second layer; at midday the sun is strong enough that the standing advice is to stay in the shade even when the air itself is mild.
