It depends on what part of the cruise you're referring to. Near Southampton it will of course be near the local temperature for that time of year - maybe 20-25C. By the time you're in the North Atlantic, it'll be a lot cooler, maybe 10C or less. You'll definitely need a jacket at night. And when you get to New York, if it's like most Julys it'll be hot and humid - 25-32C and 70% humidity.

I myself have made the transatlantic crossing several times.
Crossing Brooklyn Ferry was created in 1855.
In 1947, the journey by ship from Southampton to New York typically took about 7 to 10 days, depending on the specific vessel and weather conditions. Transatlantic liners, such as the Queen Mary or the Queen Elizabeth, were among the fastest options available at the time. Travelers often enjoyed a leisurely experience on board, with amenities and entertainment during the crossing.
I wanted to visit Europe, so I took a transatlantic flight to London. The first transatlantic flight took place in the early 20th century. The Titanic was unable to complete her first transatlantic crossing. My international communications still rely on the transatlantic cable.

In 1880, a transatlantic crossing typically took between 7 to 14 days, depending on the weather conditions, the specific route taken, and the type of vessel used. Steamships, which were becoming more common, could make the journey faster than traditional sailing ships. The introduction of more advanced ships and improvements in navigation contributed to gradually reducing crossing times during this period.
