You are right Steve, more or less similar. Today is bright sunshine and cold - this mornings ride in was 36F (2C) whereas on Saturday it was rainy all day (though kind of warm - 64F, (17C)...but generally more or less similar but we probably have more blue sky/sunshine days in Boston than in England (thinking of my time in Oxford) and definitely more in than in Scotland.
However as odd as it may seem, I do miss riding in the dark, wet streets of Glasgow where I used to ride year round.
cheers
