Trabzon is green for a reason: it rains all year, but summer and early autumn are the driest times.
Mild and wet, with the mountains still snowy. May is pleasant but showery.
Warm and humid at 25 to 28°C, the driest season and the time the plateaus open. Busy with Gulf and Turkish visitors in July and August.
September and October are the best months, with clearer skies, the hazelnut harvest and autumn colour in the valleys.
Cold, wet and often grey, with snow in the mountains. Sümela can close in bad weather.
June, September and October. Pack a raincoat whatever the month.
