In every area where earthquakes are common there is a belief that earthquakes are more common in certain kinds of weather. In fact, since geologists have been collecting data no correlation with weather has ever been found. Earthquakes originate many kilometers (miles) below the region affected by surface weather. Things like wind, precipitation, temperature, and barometric pressure changes affect only the surface and shallow subsurface. Earthquakes are focused at depths well out of the reach of weather, and the forces that cause earthquakes are much larger than the weather forces.
Another common belief is that earthquake occur in the mornings. In fact, several recent damaging earthquakes have been in the early morning, e.g. the 22 Dec 2003 San Simeon 6.5 event was at 11:15 AM. The 17 Jan 1994 Northridge quake 45 sec and a 6.7 shaker and of course the famous San Francisco quake 18 April 1902 at 5:12 AM and 7.9 estimated. As a result many people believe that all big earthquakes happen in the AM. In fact, earthquakes occur at all times of day. The 1933 Long Beach earthquake was at 5:54 pm and the 1940 Imperial Valley event was at 8:37 pm. More recently, the 1992 Joshua Tree earthquake was at 9:50 pm. It is easy to notice the earthquakes that fit your preconceived pattern and forget the ones that don't
Some recent research has found a correlation between a sudden relative spike in atmospheric temperature 2-5 days before an earthquake. It is speculated that this rise is caused by the movement of ions within the earth's crust, related to an oncoming earthquake. However, the atmospheric changes are caused by the earthquake, rather than causing it. Furthermore, this relative change would not cause any single recognizable weather pattern that could be labelled "earthquake weather".

At the 2011 American Geophysical Union Fall Meeting, Shimon Wdowinski announced an apparent temporal connection between tropical cyclones and earthquakes.

In April 2013, a team of seismologists at the Georgia Institute of Technology re-examined data from the 2011 Virginia earthquake using pattern-recognition software and found a correlation between hurricane Irene's nearby passage and an unexpected rise in the number of aftershocks.

Any person who proclaims its earthquake season is deluding themselves.
Glad to hear no one's been seriously hurt (rattled nerves aside) although broken wine bottles can be considered a tragedyHi Graugeist, thanks and so far nothing too bad, just a whole heap of broken wine bottles and stuff falling off shelves. Hopefully it won't get much worse. Aaron (Gumbyk) is only 30 or so Ks from where the most intensive activity has been happening. I have a house over there too and I haven't heard from my tenants, so they must be okay.
