fixed the issue. Will look into that further Getting this sort of information is basically pretty slow. To quote the great Louis C. K. "It is going to space, give it a second". Because you've specified PositionAccuracy.High this means that the location must be found using GPS, which is comparatively slow, and not any of the faster fallback methods such as using local wi-fi or cell phone towers.
You could reduce your demands for accuracy overall or initially request a lower accuracy and then refine it once the information from the GPS is available. The second option is better. If you look at a map application they typically do this by showing you about where you are and then improving it after the GPS lock is acquired.

I hope this helps you .
I was thinking: this means I'm retrieving the same data each time a page is first activated. Is this 'best practice'? Is it more reasonable to only load the data once? But how does this work?

help you fix your problem Add a scoping function (an IIFE) that creates a new scope for your variable:
code :
function buildCities()
    for (var i = 0; i < 7; i++) 
            var jqxhr = $.getJSON("http://api.openweathermap.org/data/2.5/weather?q=usa,phoenix&units=metric", function(response)

$.getJSON("data.json",function (data) {
