My husband and i will be in be in Dubrovnik at the end of September and I was wondering what the weather is like around that time of year. Will it be warm enough to swim and sunbathe.
Yes, end of September is still good for swimming and sunbathing! Sometimes even the start of October is warm enough for swimming, but you can't predict weather.
That's how usually and most of the time is, but there's no guarantee it will be.
I've always experienced good weather in September but as the weather is changing throughout the world there is no guarantee. Should be fine though.
