Alright Bob, my name isXXXXX for the delay I lost what I was typing to you and had to retype.
So generally speaking the weather at elevation around the equator is going to be pretty darn consistent, the lower elevations are usually what are most subject to more variation.
For both cities in Ecuador that you are looking at you are going to need to basically pack for a North American type of spring and some rain gear. The weather, because of the elevation is going to be warm and sunny during the day, cooler at night.
Obviously if you checked the weather right now you could see a forecast of possible thunderstorms and rain, but the reason these places are becoming a "hot spot" or sorts is simply because they are so consistent. Its almost like they are the "San Diego" of S. America with slightly cooler nights. If you needed more "summery" weather you could just head south out of the elevations.
If you are packing, I would pack for a traditional spring, shorts and summer wear for the days, light layers or sweaters and long pants for the night. Since you mentioned planning on hiking presumably at different elevations, I would pack lighter, stripable layers, shorts and rain gear with a hood if you have it just in case you move away from these places for your hikes and you are caught in a downpour. Obviously boots with your rain jacket for the hike but light things that would protect you from the sun as well as more layers in case it gets later or darker. So in short, a "spring" mix.. just in case you hit some rain.
Both cities are considered really consistent weather wise and that is because they don't have the latitudinal fluctuations like any of the Canadian territories and because they are so high in elevation.
I can already see myself retiring here..
