What is the ideal way to implement this PHP / XML feature on a website?

Question

I have this code written to snatch some weather data and make it available on my website:

if( ! $xml = simplexml_load_file('http://www.weather.gov/data/current_obs/KBED.xml') ) 
{ 
    echo 'unable to load XML file'; 
} 
else 
{ 
  $temp = $xml->temp_f.' Degrees';
  $wind = $xml->wind_mph;
  $wind_dir = $xml->wind_dir;
  $gust = $xml->wind_gust_mph;
  $time = $xml->observation_time;
  $pres = $xml->pressure_in;
  $weath = $xml->weather;
}

And then I just repeat them inside the tags that I want them inside. My site is low in traffic, but I am wondering what the “best” way to do something like this is if I sway in traffic. Do I have to write these variables that I want to get to the database every hour (when the XML is updated) with a cron job to save the pinging server every time, or is this not a bad practice? I understand that this is a bit subjective, but I no longer need to ask for "better ways." Thanks!!
