Apparently if you go to India you should get a good view. Europe seems to miss out this time as the place in the sky where the shooting stars appear is below the horizon in Europe when the likely maximum rate occurs. My former colleagues are predicting about 300 shooting stars an hour at the peak.
But it's not a very exact science so if it's not cloudy it's worth having a look as soon as it gets dark on Tuesday night up to about midnight. Even if the rate has dropped below the maximum you should get to see about one bright meteor every five minutes or so. Not quite as spectacular as the Leonid display in 1799 when there were tens of thousands of shooting stars. Anyway, I've never seen the Leonids - it's always been cloudy when they turn up in November!
