What's the difference of four or five degrees between Baidu weather forecast and central weather bureau network forecast?

Weather forecast is a forecast, just like the original data, different forecasts can be obtained from different angles, and the key is who considers the details closer to reality.

The weather forecast must be based on local data. Central weather bureau is a large-scale forecast, the specific location depends on the local forecast. Baidu's weather forecast is generally based on local forecast data, so its credibility will be higher.
