About This Outlook
As part of our ongoing commitment to protect mariners' lives and help in times of crisis, Weathernews previously provided daily and weekly port weather highlights for the Strait of Hormuz and the Middle East. With the change of seasons and the onset of the Southwest Monsoon, we are now shifting our focus to port forecast snapshots across the Indian Ocean and South Asia — offering this as a reference for the public and stakeholders monitoring monsoon progression and adverse sea conditions in the region.
Reports are updated four times daily and include 48-hour, 5-day and 7-day outlooks for your use.
Weathernews Maritime Forecaster comment:
Under the influence of the summer monsoon, southwesterly winds are prevailing in both the Arabian Sea and the Bay of Bengal.
In the Arabian Sea, winds are blowing strongly at 25–30 knots, particularly in the northern region, and from the 17th onward, there are periods when winds are expected to temporarily reach 30 knots. Significant wave heights are at 3.5–4.5 meters in the northern part, and from the latter half of the week through the weekend, heights could rise to 4.0–5.0 meters in some areas.
In the Bay of Bengal, southwesterly winds of around 15–20 knots are expected to remain relatively stable throughout the period. Significant wave heights will be around 2.5–3.5 meters, with a tendency to settle slightly to around 2.0–3.0 meters heading into the weekend.
