You'll find dozens of weather reporting services online, but all of them give you the weather in the traditional old sunny/cloudy/raining kind of way. None of them, however, will tell you if today will be as pleasant as Naboo.
Star Wars weather isn't a revolutionary way to check the weather report, but it's a nice diversion from a lifetime of "partly cloudy with a chance of rain". Rather than simply reporting the weather and forecast, Star Wars Weather gives you the conditions based on the climates and conditions of locales in the Star Wars universe like Hoth, Naboo and Endor.
If you know of a fun site for sharing information in an unconventional way — stock quotes via Shakespeare perhaps, like "True is it that we have seen better days." — let's hear about it in the comments.
