A: 

When depending on external web services it is best to load asynchronously so that if one of them is slow you can show some kind of loading spinner to the page viewer. If it fails your page could simply report that reading from the web server failed and to try again later.

In this case I would load up the page with the Google map in place and then make an AJAX request for the Weather data.
