Croatia honeymoon

Hi all! Currently planning my honeymoon for October 2025. Due to our work schedules we’ll be honeymooning for a week so won’t be able to go long haul (from the UK). Our favourite place we’ve been to as a couple has been Dubrovnik. It’s really special to us and we’ve been thinking about going again for our honeymoon. However I’ve heard mixed things about the weather that time of year. We’ve both rather fair so not bothered about sweltering heat but one the things we most enjoyed last time was jumping in and swimming in the sea around the city walls. If the water is too cold for this I feel like we’d definitely need to look at a different destination. We’ve also been been looking at Rhodes and other areas of Greece but would love some advice on this because as I’ve mentioned Dubrovnik is really special to us and we’d love to go again.
