No. An incoming meteor or asteroid is perfectly ecumenical with respect to location, therefore the vast majority of meteors fall into the oceans.
On a related note, the best time to see meteors is between midnight and dawn in whatever location you find yourself. The reason? At dawn, if you look straight up, you're looking in the direction Earth is moving in its orbit at thirty kilometers per second. By contrast, if you look straight up at sunset, you're looking at where Earth has just been and is receding from at thirty kilometers per second. Earth's velocity is added to that of the wandering space rocks near dawn, but is subtracted at sunset.
