North and South Winds in Kuwait

Kuwait's sea answers to two winds: the shamal that blows from the north and northwest, and the kous that creeps up from the southeast. Wave height, visibility, water temperature and even the mood of the fish all follow whichever wind owns the sky that day.

Read them wrong and you fight the sea all the way home. Here is what each wind does to the water, what it means for fishing, and how to check the forecast before you commit to a trip.

The Shamal: Kuwait's Signature North Wind

The shamal is the wind Kuwaitis know best. It is cooler and drier than the air it replaces, and it scrapes the sky clean — the clearest visibility of the year usually comes on shamal days. In summer it can hold for days at a stretch, strongest through the middle of the day and easing by evening.

For boats, a moderate shamal is no problem — it even helps, pushing you out and carrying you home. The trouble is a hard shamal, which piles a short, sharp chop onto Kuwait Bay that small boats feel in full. It rarely ambushes you though: the shamal builds gradually and forecasters track it days ahead. Fishermen love the aftermath — after a couple of shamal days the water cools and clears, and the fish switch on. Some of the best zubaidi and grouper runs come as a strong shamal settles.

The Kous: Warm and Humid From the Southeast

The kous is the shamal's opposite. It arrives from the southeast carrying warm, humid Gulf air, mostly from late autumn through early spring, and it can build within hours — a calm morning can turn into a chopped-up sea by lunch. If it has crossed the desert first, it drags dust with it and visibility drops fast.

Respect the kous on the water. Its waves run shorter and steeper than shamal swell, riding harder in a small boat, and its haze complicates navigation. It is not all bad news: the warmth and stirred-up water can wake up inshore fish, and some locals deliberately fish the edge of a kous. Treat it like a weather front — know when it hits, and never get caught on the wrong side of it.

Read the Forecast Before You Launch

Before you leave the harbour, spend two minutes reading the water. Check the wind speed and direction for the whole day — not just the morning — and the sea state it will produce.

• Wind direction and speed — a steady shamal day is workable; a strengthening kous needs a plan.
• Sea state — wave height, and whether the sea is choppy or rolling.
• The trend — is the wind building, holding, or easing by the time you head back?
• Visibility — dust warnings matter as much as wind speed when the kous is blowing.
• Your boat's limits — if the forecast tests them, wait a day.

You do not need a marine-forecast course. The B7R app puts sea state, wind and tide times for Shuwaikh and Shuaiba ports in your pocket, so you can see a kous forming or a shamal building before it reaches you.

Match your trips to the wind: know what the shamal and the kous each do, check conditions before you launch, and log your catches in the B7R app so your own experience sharpens the picture. Plan around the sea and it will treat you right.
