Is the weather forecast on iPhone accurate?

So far, the most accurate weather forecast in the world is the U.S. Navy weather forecast, which is accurate within 3 minutes and generally 7 minutes. As a commonly used production or daily weather forecast, the accuracy is generally within 7 hours. General weather forecast programs have been available for more than 72 hours, and their accuracy varies with the season. About 30% in summer and about 60% in the other three seasons (I forgot which magazine I saw it in.)

In short, humans have not fully understood many natural phenomena similar to weather changes. However, it is spring now, and I don’t know if the poster is from the south or the north. If you are from the north, the weather forecast should not go too far. If it is summer, even if it is reported tomorrow or this afternoon, you should be suspicious. This is not to say that he is 100% accurate. After all, after the launch of the Asia-5 weather satellite, my country's weather forecast has undergone qualitative changes.
