I wouldn't recommend the equator, it really is too hot. Now the tropics, that's OK, especially if you're up above a certain elevation because the wind can have a very pleasant cooling effect. And of course mosquitoes can't fly in the wind.
But you might still need to factor in the cost of air con. Although sleeping under the stars in a light wind is to be recommended, and mosquito nets are extremely effective.
And your gas for cooking will probably be bottled, so you'll need to factor in transport and higher prices for that.
You can, of course cook on an open fire, or a fire pit. A properly designed fire pit is very convenient, but the preparation times are extended, and you'll still need to factor in the fuel.
And of course, the seasons are not winter, spring, summer, etc, it's wet or dry. But the temperature stays about the same, so it's either humid or it's not.
