'Places near the equator have warm weather even in the cold season.' Why is the article 'a' incorrect before 'warm weather'?

Weather is a mass noun, which means it cannot take the indefinite article a/an alone.
The article "a" can only be attached to mass nouns when a quantifier specific to the noun is used.

A spell of warm weather.

Other examples of mass nouns include air, grass and happiness.

  • This isn't a reliable rule, in either direction. The count-noncount differentiation hinges on the availability of using a numeral in the usage [CGEL]. Thus 'A subtle light flooded the clearing' (but not 'Three subtle lights flooded the clearing') / 'The state gave me a good education' (but not 'The state gave me two good educations'). 'I have an understanding of the principles involved' (but not 'I have two understandings ...') / 'I felt a strange warmth' (but not 'They felt two strange warmths') all show noncount usages. – Edwin Ashworth Aug 08 '17 at 10:14
  • 'He has an excellent knowledge of Italian' can't possibly be classed as a count usage according to the authors of CGEL. Take a look at the duplicate. – Edwin Ashworth Aug 08 '17 at 10:20
  • @EdwinAshworth I don't really understand what you're trying to say, but mass nouns can't take the indefinite article. – as4s4hetic Aug 09 '17 at 08:29
  • You're missing a vital piece of the explanation in the linked ODO article: 'usually '. See my answer here. Quirk et al (p 252) have 'It can be argued that some nouns, like weather, are neither count nor noncount, but share features belonging to both classes ...'. – Edwin Ashworth Aug 09 '17 at 08:58
