Is the weather forecast for Hefei in the next 40 days accurate?

There is not much deviation in the general trend. I think it is enough to arrange some future plans.

First of all, the 40-day weather forecast of any software can't be very accurate, which is the limitation of the existing technology .. So I think we can use appropriate and loose standards to judge whether the 40-day weather forecast is accurate enough. For example, when I use this function, I want to know more about the general trend of temperature and precipitation in the future. As long as the general situation is similar, I think it is accurate enough. Obviously, ink weather has satisfied this point.
