Name of Seasons in Capital Letters

[demarines]

Is it a mistake not to capitalise the name of the seasons?

[Neillythere]

As a Brit, but not a teacher, I would reference the Oxford English Dictioary entry, which identifies summer without a capital letter, as follows:

summer

• noun the season after spring and before autumn, when the weather is warmest.
• verb spend the summer in a particular place.
— DERIVATIVES summery adjective. — ORIGIN Old English.

If it's good enough for Oxford, it's good enough for me!

Most style guides will tell you to NOT capitalize.
