What do you mean? It gets the weather for your city via your IP address, maybe you're on a VPN.
Your IP address doesn't automatically correspond to your city, even without a VPN.
Then add your city as an argument to the curl. It works well enough regardless and doesn't use hundreds of megabytes of RAM which is what the initial complaint was.
That's a pretty crappy way to detect it seems, it thinks I'm in some city almost a thousand miles away, no VPN, purely direct connection,...
