Warm water surfing in August

Hi everyone,
I put off my June trip as I couldn’t not decide on somewhere to go, and am now trying again
I am looking for somewhere to go in August-September, that has backpacking options, sunshine, and lots and lots of good surf. I have given up on finding my ideal location but it would be lovely if the water was 23 degrees+, light winds, and there was some sort of city/urbanisation (I’m going alone).
If anybody has any ideas, or opinions about the following places Ive been researching, I would really appreciate it!
- Bali
- Oahu
- Gold Coast
- Sayulita
Thanks so much in advance
