The quality of the sunset depends on the person next to you :-) At 9pm it is usually dark. Temperatures are usually well below 30°C. However the sea is warm enough.

the very beginning of September is great, not tooh ot, but sunny and funny:) try Yalta, very nice Ukrainian place, I love it. sea is great, food - fine and very warm and friendly people.

Don't wait too long. I was once in Odessa on October 30th, it was freezing minus 8 at night and the hotel's central heating was switched on only from November 1st onwards!

September is the best time to come to Crimea. not yet cold and not hot. ifyou need any information - write me an e-mail,i am the professional guide around Crimea - moirizar@gmail.com. i will help you with your visit, hotels and your stay here.

It's not that hot in September any more - anyway it wasn't boiling hot for me. Try to get to Bkhchisaray - it's a very nice city in the center Crimea, a former capital of Crimean Khanate. It's very eastern, great local food. Nearby is a mountain fortress of Cufut Qale - "Jewish Fortress" - really worth seeing it!

What about the sunset? is it dark very early? and temperatures? less than 30?

I spent time in Sevastopol in September. It is the best time to get there I guess, although there were some short heavy rain showers. Yalta is nice. However, I didn't like the beaches - no sand, just shingle beaches. Beware that hardly anybody speaks foreign languages. The preferred language is Russian, not Ukrainian.
