Questions & Answers about Wrzesień bywa ciepły, ale wieczorem jest już zimno.
Yes — month names in Polish are normally written with a lowercase letter: wrzesień, październik, maj.
Here it is capitalized only because it is the first word of the sentence. If the month appeared in the middle of a sentence, it would usually be wrzesień, not Wrzesień.
Bywa means something like can be, is sometimes, or tends to be at times.
So:
- Wrzesień jest ciepły = September is warm
- Wrzesień bywa ciepły = September is sometimes warm / can be warm
This adds the idea that it is not always warm, but that warm September weather happens from time to time.
Bywa comes from bywać, which often expresses repeated or occasional states/events.
