Saudi Aramco is building a 400,000 bpd refinery with associated terminal facilities on the Red Sea near the city, scheduled for completion in late 2018.

[6] Today, ambitious projects in transport, renewable energy, tourism and agricultural development are taking place in the Jizan region, particularly in Jazan Economic City, including a US$3 Billion aluminium smelter.

[citation needed] Furthermore, the southern and western outskirts of the city are a place which the Kingdom wants to turn into its agricultural hub due to its underground water resources as well as the rich and diverse soil.

The Refinery will process heavy and medium crude oil to create liquefied petroleum gas, sulfur, asphalt, benzene, and paraxylene.

Jizan has a hot desert climate (Köppen: BWh) with a rainfall below 200 mm per year and an average annual temperature above 30 °C (86 °F).
