NAME

Weather::Meteo - Interface to https://open-meteo.com for historical weather data

VERSION

Version 0.09

SYNOPSIS

      use Weather::Meteo;

      my $meteo = Weather::Meteo->new();
      my $weather = $meteo->weather({ latitude => 0.1, longitude => 0.2, date => '2022-12-25' });

DESCRIPTION

Weather::Meteo provides an interface to open-meteo.com for historical weather data from 1940.

METHODS

new

    my $meteo = Weather::Meteo->new();
    my $ua = LWP::UserAgent->new();
    $ua->env_proxy(1);
    $meteo = Weather::Meteo->new(ua => $ua);

    my $weather = $meteo->weather({ latitude => 51.34, longitude => 1.42, date => '2022-12-25' });
    my @snowfall = @{$weather->{'hourly'}->{'snowfall'}};

    print 'Number of cms of snow: ', $snowfall[1], "\n";

weather

    use Geo::Location::Point;

The date argument can be an ISO-8601 formatted date, or an object that understands the strftime method.

    my $ramsgate = Geo::Location::Point->new({ latitude => 51.34, longitude => 1.42 });
    # Print snowfall at 1AM on Christmas morning in Ramsgate
    $weather = $meteo->weather($ramsgate, '2022-12-25');
    @snowfall = @{$weather->{'hourly'}->{'snowfall'}};

    print 'Number of cms of snow: ', $snowfall[1], "\n";

    use DateTime;
    my $dt = DateTime->new(year => 2024, month => 2, day => 1);
    $weather = $meteo->weather({ location => $ramsgate, date => $dt });

Takes an optional argument, tz, which defaults to 'Europe/London'. For that to work set TIMEZONEDB_KEY to be your API key from https://timezonedb.com.

ua

Accessor method to get and set UserAgent object used internally. You can call env_proxy for example, to get the proxy information from environment variables:

    $meteo->ua()->env_proxy(1);

You can also set your own User-Agent object:

    use LWP::UserAgent::Throttled;

    my $ua = LWP::UserAgent::Throttled->new();
    $ua->throttle('open-meteo.com' => 1);
    $meteo->ua($ua);
