I've read that the SW part of England (due to its pleasant climate) is
a big vacation (holiday) destination for city folk in England. I
suspect that the locals are not too fond of this fact.

Hmmm, the locals may moan (as I have done occasionally when you can't move
for visitors) but it brings in an awful lot of money to the economy of the
South West. You have to take the rough with the smooth; the main holiday
'season' only really lasts 6 weeks so you have the rest of the summer to
enjoy without the crowds.

The first big influx of visitors starts with Easter and it can be quite a
shock to the system after having to deal with just local traffic over the
winter. Then things get back to normal after Easter until Whitsun, when it
can get very busy again. But none of this compares to when the schools shut
for summer around the 3rd or last week of July. All the campsites, holiday
cottages, hotels, B&Bs, guest houses etc etc are usually full to the brim
for the whole of the 6-7 week school holiday duration. August Bank Holiday
(last weekend in August) is when most holiday-makers return home.

If any of my friends/relatives are visiting us for the a summer/beach break
I always recommend June up until mid-July, or the beginning of September. It
is amazing in September with still quite hot days and the sea at its
warmest; this is the best time as the beaches can be quite empty whereas
just a few weeks' earlier the beaches would have been very busy indeed.
