Weather Forecast

Here is the weather forecast for Hanoi for the next few days, taken from three sources.

(A good History student must always keep a look out for a variety of sources!)

Source B: http://www.freemeteo.com/default.asp?pid=23&gid=1581130&la=1

Source C: http://weather.yahoo.com/forecast/VMXX0006_c.html

Question: So, what can you infer about the weather in Hanoi from these three sources? :)
