Questions & Answers about August kan være varm.
They are usually lowercase in Norwegian: januar, februar, mars, august.
Here, August is capitalized because it is the first word of the sentence. In Norwegian, the first word of a sentence is capitalized just like in English.
So in the middle of a sentence, you would normally write:
Jeg liker august.
In this sentence, it is understood as the month of August.
August can also be a male first name in Norwegian, but the context here points to the month, especially because varm means warm, which fits naturally with a month or time of year.
Norwegian normally does not use an article before month names.
So you say:
august er varm = August is warm
not something like den august
Month names behave more like proper names in this kind of sentence.
