Hot weather at Southend, just as at Hampstead (5)
I believe the answer is:
heath
'southend just as at hampstead' is the definition.
I can't judge whether this defines the answer.
'hot weather' is the wordplay.
'hot' becomes 'h'.
'weather' becomes 'eath' (I am not sure about this - if you are sure you should believe this answer much more).
'h'+'eath'='HEATH'
'at' is the link.
Can you help me to learn more?
(Other definitions for heath that I've seen before include "See 16" , "Tract of open land" , "Moor" , "Moorland shrub" , "Area of open land with gorse etc" .)
