y configura la siguiente linea, coloca la direccion URL de tu proveedor del Tiempo en XMl o Rss
------------------------------------------------------
$fp = fopen("http://www.ibs.org/dm/syndicate/rss/niv.xml", "r");
if(!$fp) {

Luego en su index.php inserta esto:
<?php require("include/tiempo.php"); ?>
y dondequiera que te salga el estado del tiempo pega esto
<?php echo $weather;?>
Espero que sea lo que buscas.
