Tigrai has two seasons; the dry season prevailing from October through May, and the wet season, which runs from June to September.Temperatures are determined by altitude, with highlands rarely exceeding 25º C. In the lowlands it can get considerably hotter exceeding 40ºC, while in the Danakil Depression it can approach 60ºC.

Light, summer clothes are suitable for daytime wear and a jacket or sweater is useful for the evening when the temperature is much cooler. Visitors to Ethiopia in the rainy season are reminded to pack suitable clothing. Footwear for walking expeditions and visiting historic sites should be light but strong, thus sandals are not recommended
