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. Finally, longer term forecasts, i.e. a week ahead or longer, are usually not available. The responses to my article varied greatly.
