Do the seasons (summer, autumn etc.) require a capital letter?
The seasons do not need a capital letter and there is ample support for this usage in the following books.
Concise Oxford English Dictionary (2004)
Oxford Dictionary for Writers & Editors (2000)
Oxford Guide to Style (2002)
The last of these says capital initial for seasons only when personified which really amounts to only in poetry.
It is all part of the trend to plainer English which includes fewer capital initials.
