I insist on encryption so this is what I use:

server {
listen 80;
server_name yourdomain.com www.yourdomain.com ;
if ($request_method !~ ^(GET|HEAD)$ ) {
return 444;
}
return 301 https://$host$request_uri;
}

I only serve static pages so I use that filter. Obviously that is
optional. But basically every unencrypted request to 80 is mapped to an
encrypted request to 443.
