This table allows the comparison of historic, current, and future weather conditions for some locations of interest.
Every country has a national weather centre, or so-called, meteorological office.
Not necessarily every such office will have a web site. Historical data is usually more difficult to come by, than current or forecasts. Current weather conditions on the web refer to the latest available - rarely real time continuous basis. Forecasts, on the other hand, are readily available for the day, next day, or day after. However, accuracy and reliability vary greatly.
