Nicaragua is just like any other Latin American country. We dress the same and we are maybe even too friendly. That is something that you need to know if you are not a friendly person because here we might meet and then half an hour after, we will treat already treat you like our best friend. If you don’t like that, you can say it upfront and we can respect that.
If someone does not speak Spanish, we don’t care and we don’t mind. Some expats think we do mind so they try to explain things using Spanish words, but pronounce it like English so the translation becomes very funny.
Regarding customs, we know if you are a tourist because tourists wear shorts, sandals, and t-shirts because of the heat. It is really warm here in Nicaragua. Nicaragua is the warmest country in Central America.
I can’t think of anything that you can do that will offend a Nicaraguan, except if you make a negative remark about Nicaragua. Even if we know that it is true, we don’t like that kind of comment. I think that is just the same anywhere in the world.
If you were invited to have a meal at a Nicaraguan’s house, you can bring with you a bottle of drink or some homemade food and we would really appreciate that. One thing about Nicaraguans is that we are not punctual people. If the get together is at 7 PM, we would clean the house at 7 PM, take a shower at 7:30 PM, and be ready at 8 PM. We are usually an hour late from the agreed time, which is equally true for business dealings, as it is with family affairs. If you agree to meet with a Nicaraguan at 6 PM, he might be there at 6:20 PM, so you just have to get used to that. We don't get insulted when someone shows up late for a meeting, so we expect the same from expats or tourists.
