I believe the answer is:

rainy

I'm a little stuck... Click here to teach me more about this clue!

'no weather' is the definition.
'rainy' can be an answer for 'weather' (thesaurus). I am unsure of the 'no' bit.

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for rainy that I've seen before include "Save your money for this damp day" , "(Of weather) wet" , "Drizzly" , "With water falling outside" , "Pluvial" .)

I've seen this clue in the Evening Standard.
