If you're using JQuery then you could use a defer and promise. Something like this:

function getWeatherData(latitude, longitude) {
    var temperature = 0;
    var dfd = $.Deferred();
    var url = "http://api.openweathermap.org/data/2.5/weather?lat=";
    url += latitude;
    url += "&lon=";
    url += longitude;
    url += "&cnt=1";
    $.ajax({
        type: "POST",
        dataType: "jsonp",
        url: url + "&callback=?",
        async: false,
        success: function (data) {
            temperature = data.list[0].main.temp;
            alert(temperature);
            dfd.resolve(temperature);
        },
        error: function (errorData) {
            alert("Error while getting weather data :: " + errorData.status);
        }
    });
    return dfd.promise();
}

This will cause it to return the value once temperature has been resolved through the ajax call. I was using a weather API and had this same exact problem.
