Where can we go Sep/Oct?

[LadyKyliePonsonbyFarquhar]

We are looking for ideas for a holiday end of September/beginning of October for me , DH and DDs 19 and 22. We are considering Greece (not sure if ferries will still be operating between islands) Croatia (are all the beaches pebbly?) Turkey, Canary Islands, and Mallorca. Where will the weather still be hot? We want to chill out on the beach, some local culture and some night life/nice restaurants but not too many brits. Any other destination ideas welcome. I think we will be looking to rent a villa or air bnb.

To get guaranteed hot sunshine the Canaries is best. Turkey would also be still pretty hot at that time. Majorca can be wet in October but equally can be scorching. Same applies to the more Northerly Greek islands. I'd head down towards Rhodes / Crete if I was going in October.
I've been to Croatia in September and had a cloudy week but I'm sure others will have had sunshine. I've never seen much of a sandy beach in Slovenia / Croatia.

I am taking DS20 and 22 on holiday with us so understand the need for some nightlife v not touristy, it's a tall order.

Been to Rhodes at the middle of October and it was still hot.
Canaries will obviously still be hot but not very cultural.
Turkey should still be hot. We're going to Fethiya in July.
My Ds and Ddil have been and recommended it.
Not loads of Brits. Quiet if you want but also nightlife.

We did the Canaries last Oct and it was lovely and hot.
Also, everything was still open, felt like we were yhere in June or July, just without it being chaotically busy.

Looks like Canary Islands would be best for guaranteed good weather. So which island now? We have been to Tenerife, so maybe Lanzarote?

Lanzarote is lovely !

Playa Blanca, Lanzarote. Done!

I like Lanzarote and we took DS(20) in March to Puerto Del Carmen. It has good nightlife but is a bit British. Playa Blanca is great for families with small children (though I didn't like it) but is dominated by all inclusive hotels and not much nightlife.
We are going to Corralejo in Fuertaventura with adult DC this summer. It has the best beaches I've ever been to in Europe and is a lively little town with good nightlife. Again a bit British though. Good for surfing though not much culturally.
