The Muscat International Airport reopened after three days while Fujairah reopened on June 7 after it was closed the day before. The cyclone caused little impact to oil facilities along its path; after the initial price rises, oil dropped over US$2 per barrel as a result. Across the northern Arabian Sea, the passage of Gonu produced stronger winds and significant upwelling - an oceanographic phenomenon that involves the replacement of the nutrient-depleted surface water with deeper nutrient-rich water; the passage caused a significant increase in phytoplankton. Additionally, the cyclone delayed the arrival of the Indian Ocean south-west monsoon in the Western Ghats in India.
