Stormy waves on the open ocean — The North Atlantic is roughest from November to March.

The North Atlantic

The UK–North America route is the most popular, and also the most seasonal.

Summer (June to August): usually the calmest, with long daylight hours
Spring and autumn: good value and fewer passengers, with occasional rough days
Winter: frequent storms and big swells. Experienced sea travellers enjoy it, but it is not for the seasick.

Read how long it takes to cross the Atlantic by ship und boat from the UK to the USA.

Asia and the monsoon

On Europe–Asia voyages, the southwest monsoon (about June to September) brings strong winds and big swells in the Arabian Sea and Indian Ocean. Between October and April conditions are generally much calmer. See cargo ship to Singapore und cargo ship to China.

Calm ocean — Late spring and summer usually bring the calmest seas.

Australia and New Zealand

The southern summer (December to February) is warmest. Voyages through the Southern Ocean in the southern winter can be rough. See ship from England to Australia.

Hurricane and typhoon seasons

Atlantic hurricanes: June to November, peaking August to October
Western Pacific typhoons: mostly May to November
Indian Ocean cyclones: vary by region

Ships track storms carefully and change course or speed to avoid them, but this can delay your arrival.

Other things to consider

Daylight: northern routes have long days in summer and short ones in winter.
Availability: summer voyages fill early, so book ahead.
Preis: off-season voyages can be easier to get.
Seasickness: if you suffer, choose the calmest season. See Seekrankheit auf einem Frachtschiff.
