Climate & Weather Guide in Iraq

Climate zones, seasonal temperatures, rainfall patterns, and best travel times

Iraq features a predominantly hot desert climate with extreme summer heat and mild winters, influenced by its position between the Arabian Desert and the Persian Gulf. The country spans three main Köppen climate zones: hot desert (BWh) in the west and southwest, hot semi-arid (BSh) in the east near the Gulf, and cold semi-arid with dry summers (Dsa or Csa) in the northern mountains. Annual rainfall is very low overall, ranging from under 100mm in deserts to 400-800mm in the north, with scorching summers often exceeding 45°C and cool winters around 5-10°C. Low humidity and abundant sunshine prevail, but sandstorms pose risks. Recent data confirms intensifying heat due to climate change, making air conditioning essential for residents.

Regional Climate Variations

Western and Southwestern Desert

This vast arid zone, classified as BWh hot desert climate, dominates Iraq's interior with relentless dry heat. Summers soar to 45-50°C, while winters remain mild at 5-15°C. Rainfall is negligible at under 100mm annually, leading to barren landscapes and frequent sandstorms from hot desert winds. Expats should prioritize heat-resistant housing and hydration; nights cool significantly, offering relief.

Summer:35-50°C

Winter:5-15°C

Very low rainfall

Scorching days with extreme low humidity create a harsh, dusty environment ideal for solar power but challenging for outdoor activities without protection.

Eastern Lowlands and Gulf Coast

Covering the southeast near the Persian Gulf, this BSh hot semi-arid zone experiences high humidity from Gulf influences alongside intense heat up to 45°C in summer. Winters are cooler at 8-18°C with slightly more rain around 150-300mm yearly. The climate feels oppressive due to muggy conditions, increasing discomfort for newcomers. Coastal breezes provide minor respite.

Summer:32-45°C

Winter:8-18°C

Very low rainfall

Hot and humid summers contrast with drier winters, fostering date palm groves but requiring dehumidifiers for comfortable living.

Northern Mountains and Kurdistan

Iraq's rugged north, including Kurdistan, features a Dsa/Csa Mediterranean or cold semi-arid climate with cooler temperatures and higher elevation relief. Summers reach 30-38°C, winters drop to 0-10°C with occasional snow. Rainfall peaks at 400-800mm, mostly in winter, supporting greener valleys and agriculture. This zone offers the most temperate conditions for residents seeking variety.

Summer:25-38°C

Winter:0-10°C

Low rainfall

Milder summers and wetter winters create a refreshing highland feel with scenic beauty, though chilly nights and fog demand layered clothing.

Iraq's climate varies from blistering desert heat in the west and humid lowlands in the east to milder, wetter mountains in the north, demanding adaptation like AC and water management for expats. Residents appreciate vast sunshine and short winters, but extreme summers and dust storms challenge comfort. Northern regions appeal most for year-round livability.
