Forecast.io service unavailable - php

Question

I am using forecast.io API to deliver weather data to my website. Sometimes the forecast.io API is down, which causes every single page on my website which uses the forecast.io API to return "Service Unavailable, unable to get file content errors"
This is what I'm using to gather the weather data from the API
<?php
include("assets/php/forecast.php");
$api_key = '123123123';
$latitude = $data->getLatitude();
$longitude = $data->getLongitude();
$forecast = new ForecastIO($api_key);
/*
* GET CURRENT CONDITIONS
*/
$condition = $forecast->getCurrentConditions($latitude, $longitude);
$temp = $condition->getTemperature();
$temp = $temp + 2;
$summ = $condition->getSummary();
$icon = $condition->getIcon();
$icon2 = $condition->getIcon();
$icon = str_replace('-', '_', $icon);
$icon2 = str_replace('-', ' ', $icon2);
$icon = strtoupper($icon);
$icon2 = ucfirst($icon2);
?>
I would like to include some sort of error handler where if the forecast.io API is unavailable, then this code doesn't get called.

This is the site where I had the problem
https://seek.estate/
https://seek.estate/buy/422-melbournes-most-liveable-home-sea-views-elevator-designer-masterpiece
This is what I changed
$forecast = new ForecastIO($api_key);
$request_url = 'https://api.forecast.io/forecast/';
$content = file_get_contents($request_url);
if (!empty($content)) {
return condition = $forecast->getCurrentConditions($latitude, $longitude);
} else {
return false;
}
