This year the Geminid meteor shower occur from 13th to 14th December 2013 and will peak on the 14th.
The Geminids are a meteor shower caused by the object 3200 Phaethon,which is thought to be a Palladian asteroid with a “rock comet” orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet. The meteors from this shower are slow moving, can be seen in December and usually peak around the 13th – 14th of the month, with the date of highest intensity being the morning of the 14th. The shower is thought to be intensifying every year and recent showers have seen 120–160 meteors per hour under optimal conditions, generally around 02:00 to 03:00 local time.
The meteors in this shower appear to come from a radiant in the constellation Gemini (hence the shower’s name). However, they can appear almost anywhere in the night sky, and often appear yellowish in hue. Well north of the equator, the radiant rises about sunset, reaching a usable elevation from the local evening hours onwards. In the southern hemisphere, the radiant appears only around local midnight or so. Observers in the northern hemisphere will see higher Geminid rates as the radiant is higher in the sky. The meteors travel at medium speed in relation to other showers, at about 22 miles per second, making them fairly easy to spot. The Geminids are now considered by many to be the most consistent and active annual shower. Geminids disintegrate while at heights above 38 kilometres (24 mi). Source: Wikipedia
