Two possibilities:

  1. Calculate them.

    There is a worked example, in MATLAB, on the wikipedia page of the guy that worked out how to do it: Arthur_Thomas_Doodson. It should be relatively easy to adapt it to perl, though you need sets of values for each place you want to make predictions for. These are probably available on line somewhere.

  2. Download them from an existing on-line source.

    For example, the UK Hydrological Office makes 7 days worth of predictions available for 100s of points around the world for free.

    There are almost certainly other sites that do similar.
