Accuweather will give you a 3 month forecast! I had to blink a few times to make sure I got that right. Their existing long term forecast goes to March 10, 2021.

It's worth being aware of its shortcomings, as even its 25 day forecast has been shown to be no more accurate than climatological averages.[1] They also have done some shifty stuff in the past regarding data privacy, among some other weird things.[2]

Silly Accuweather, I've heard meteorologist refer to anything beyond 10 days as "fantasyland", because forecast that far out are not really accurate.

Dark Sky (whose future is in question due to the Apple acquisition) has a Time Machine feature that lets you see weather pretty much arbitrarily far in the future: https://darksky.net/details/40.7127,-74.0059/2020-12-31/us12...

I have a degree in meteorology. I can forecast weather for the 4th of July over next 3 years (2021, 2022, and 2023). here in Chicago, Illinois.

will be upper 80s, low 90s. Chance of thunderstorms in afternoon.

Congrats, i have now predicted a typical 4th of July and will be correct more than normal. Damn i should have built a web company and sold my ideas for a bajillion dollars

I'm not saying it's accurate :)

But I still appreciate that the Dark Sky feature isn't artificially limited to a particular date. They have a nice error bar on the temperature that gives you an indication of how much it's unknown.

Joke's on you, I can do that without a degree in meteorology!

I'll give you a 10 year forecast!

Do you want it?
