Current Weather at Your Location Using Wunderground and Google Static Map APIs

I was more concerned with ‘Feel Like’ temperature and wind speeds for my neighborhood. Also, I live much close to neighboring town which is next to river, the weather app on iPhone always showed by hometown conditions in locked screen widget. All this lead me to build a custom page for my needs using wunderground APIs.

Current Weather Location using Wunderground Google Static Map APIs

Some key items before we move to the code:

  • Needs valid API key from wunderground (see
  • Needs valid API key from Google Static Maps (see
  • It used meta viewport for proper viewing on desktop and iPhone
  • I have added an icon used by iOS when page is added to Home Screen, that makes it feel like a real app 🙂
  • It open your default (and hard coded location)
  • There is a ‘ReLocate’ button that will refresh for your current geo-location. This however, works only on https. So if you do not see the red ‘ReLocate’ button, you are not on https
  • The page shows the map of you location so you get an idea which direction wind is flowing in from to prepare accordingly.

On Github

To extract code from git:

$ git clone

The PHP Code


// git clone 
 // more at

// various defualts. get the right keys
 // check
 $googleapi_key = "GOOGLE_MAPS_KEY";
 // check
 $wunderground_key = "YOUR_KEY";
 // enter location for which you check weather most often. avoids frequent geo-lookup. 
 $def_location = "IA/Cedar_Rapids";
 $p_lat = "41.9650539";
 $p_long = "-91.802762";
 // if new latitude and longitude were sent in params, use them instead of the defaults. 
 // the re-locate button send lat long of your current location and call this php file again
 if (isset($_GET["lat"]) && isset($_GET["long"])) {
 $p_lat = $_GET["lat"];
 $p_long = $_GET["long"];
 $location_url = "" . $wunderground_key . "/geolookup/q/" . $p_lat . "," . $p_long . ".json";
 // get location for the lat long sent via params
 $location_string = file_get_contents($location_url);

 $loc_city_raw = $parsed_loc_json->{'location'}->{'city'}; 
 // replace blanks with _. This is how the wunderground API understand multiworded cities.
 $loc_city = str_replace(" ", "_", $loc_city_raw); 
 $condition_url = "" . $wunderground_key . "/conditions/q/" . $loc_state . "/" . $loc_city . ".json";
