What to pack for British Isles?

Clothes: 1) good quality packable raincoat with a hood 2) zip-up fleece type vest or jacket. You can wear the zip-up fleece and the raincoat separately or together based on weather conditions. If you like birds/wildlife - bring compact binoculars (8 x 20). I like lightweight day-hiking boots and smartwool socks (medium or heavy weight). You will be walking on hills and uneven stone/concrete surfaces.

Rain gear. A good sweater. The weather is variable, and rain is often a constant companion. Also, it's often cooler than what we experience in certain parts of the U.S.

Late August and Early September in the UK and the Continent can be hot because it is still Summer. You only need a light weight weather resistant jacket. You can wear this over a cardigan or pullover sweater for warmth at night or at sea. You can carry an umbrella. Comfortable shoes are the most important item: water resistant leather with rubber soles. You can wear cloth shoes or sandals on the boat. Wear nice slacks. Remember to bring a swimsuit. I would bring a couple of skirts, so I could dress up for an occasion. Bring a hat with a tie for rain,wind or sun.

Sorry dont mean to be picky but it is Southampton not South Hampton😀

Careful Caro, I gently admonished someone previously for making that mistake. It appears I hurt their sensitive sensibilities as I received some gentle words of advice from the Webmaster. I sometimes wonder how some people manage in the big wide world and if they get upset because I've advised them the correct way to write or say the name of a city (Edinburgh is a common one, frequently pronounced in the same way one would would pronounce Pittsburgh. Personally I'd be grateful that someone advised me correcrtly in order to save me from future embarassment).

Not saying this is the case with the OP, quite possibly an auto correction.

I would want a waterproof, hooded jacket (or something longer). On a cruise you will have little time at each destination and will not want to give up sightseeing time to huddle in a cafe every time it starts to rain--which it is likely to do quite often in the places on your itinerary. It may be blustery, especially in coastal areas, so an umbrella will not always be useful, thus the recommendation for a hooded jacket. I use a soft sun hat that I've wateproofed and can wear under the hood to keep rain off my face.

Whether you need to run out and buy waterproof shoes (or waterproof shoes you already own) depends on your tolerance for wet feet. The shorter the trip, the more I'd be tempted to just take something comfortable from my closet. You may not have time to break in a new pair of shoes. But understand that it would not be shocking to have rain every day--though I imagine that would be statistically unlikely.

Thank you for the warning JC😁
