I’m not sure how many people use RSS feed viewers these days, but if you do then the forum has feeds you can use. For example:
Categories
https://discourse2.weather-watch.com/c/[category_slug]/[id].rss
Posts
https://discourse2.weather-watch.com/posts.rss
Tags
https://discourse2.weather-watch.com/tag/[tag_name].rss

Top topics (by period)
Considered period is user-independent.
All

Monthly
https://discourse2.weather-watch.com/top/monthly.rss
Daily
https://discourse2.weather-watch.com/top/daily.rss
Top topics (for a user)
Period depends on the user making the request.
