It would indeed.

Though as has been pointed out - all those islands off the west coast of Scotland enjoy similar weather (mild climate and often frost-free) as the south-west coast of England, thanks to the warming effects of the Gulf Stream. The Summer Isles fall into this category.

The problem is that it rains a lot and it can be very windy. Logan Gardens (in the film) has a huge windbreak of trees to shelter it.

And whilst it is mild in winter - it is often just the same in summer.
