The Weather Year Round Anywhere on Earth. Climate reports with the weather by month, day, even hour. Great for event and trip planning!
This site does not give actual daily weather reports, but gives a more detailed view of the climate for every city. It will give a good idea of what sort of weather to expect if you are planning on travelling somewhere in future. It can also do a comparison between two cities.
There is a toggle on the navigation bar to switch to metric values.
