Sometimes. At higher latitudes, especially North of the Arctic Circle, they are frequent and spectacular. At lower latitudes, they are less frequent and less vibrant. Periods of high solar activity on the Earth-facing side of the Sun, such as CME's, do strongly affect the intensity of aurorae, as well as the latitudes at which they may be seen. If you live in or near a large city, city lights can also overwhelm aurorae, as they never are extremely bright.
