If you garden then you may want to know your actual amount of rainfall to gauge how much watering you need to do. You'd be surprised how much rainfall can actually vary over a small area compared to a regional average.

And for people in rural areas that are not near other weather sensors, or areas that may not have regular internet connectivity or frequent outages (and coastal areas subject to storms and high winds). And of course weather nerds and sensor nerds, because those MQTT databases won't fill themselves.

Also if you get a good enough weather station you can feed the data to NOAA and improve the accuracy of your local forecasts.
