I answered about SE Asia in response to your question, basically mind reversal or change is just about the culture shock to the amazing different attitudes of living there!.
I travel to Indonesia and the pacific islands (the obscure ones) regularly. The visa requirements are always the issue, I’m assuming you are Canadian ??, so I’d be checking your eligibility for prolonged stays at ????????? You choose.
In many countries it is good to realise that no matter how frugal and within your means you are, you are much wealthier than most of the locals.
The other thing I do bring to your attention is if you are fairly new in your skills at surfing, realizing there are no lifeguards or rescue service in third world countries including the Central American countries. You need to be self sufficient in your water skills.
I can’t recommend with any real knowledge any spots in Central America but I would do my search in this manner, pick country, review surf schools and surf resorts, check out home stays and air BnB, read up on surf conditions and seasons.
A prolonged stay might cross several seasons.
Have a look at surfing atlases we have one here on Surfing Waves.
Next just hang in here other Forumites may post advice!
