A simple solution that does not involve building web pages, creating a VPN or port forwarding, is to use a file hosting such as Dropbox, Onedrive, Google Drive or similar. Even the free accounts have 2 gig of data & that is a LOT of weather information. That does not put the data onto anyone's web pages and the WiFiLogger ftp function would work with Dropbox.
That does not expose your data to anyone that you do not authorize (IN THEORY). Your isp may also provide a web accessible data space that you could use with a simple ftp command.
