The climate in London is very temperate, and the precipitation is usually very slight throughout the year. Except for the rise in temperature recently, London temperatures did not reach too much above 91.4oF.  The highest recorded temperature ever recorded in London was 100.6oF.  This was at Kew Gardens during the heat wave that hit Europe in 2003.

Snowfall is usually slight, in the past few years snow has only settled on the ground once or twice. London will receive less participation annually than Sydney or Rome. London’s downtown area that is built-up, causes a microclimate or Urban Heat Island. This is where heat is stored by the buildings in the city, and released back into the air. The temperature in this heat island is usually 5 to 9 degrees warmer than the areas surrounding it.

When you hear the term “London Fog”, you think of the big city being enveloped in fog, the way it is portrayed in horror movies. The truth is, terribly thick fog used to plague the city before the 1956 Clean Air Act, which permits the burning of only fuels that do not produce smoke. This fog was not so much an event of the weather, but one of pollution.

In 1952, from December 5th through the 9th smog rolled into London and stayed. At least 4000 people died as a direct result of the smog, and there were reports of cattle dying from not being able to breathe. Fog is caused by tiny drops of water in the air and the visibility is less than 1,000 meters. There is great trouble when the visibility falls below 50 meters.

The death rate in London even before this phenomenon was 135 people per day. On the second day of the fog that number jumped to 500 and didn’t drop below 200 for three weeks. The high incident of deaths for that long, is a clue to the fact that many of these people had their life cut short by the smoggy atmosphere.

The government of that time tried to ignore the problem and any evidence that pollution was responsible for the deaths of so many. The public did not take no for an answer and later Parliament was pushed to pass the Clean Air Act of 1956.

As it stands now, London fog is pretty much like the fog you will see anywhere. It is a bit more common closer to the areas surrounded by water, but when the sun arrives it burns off the fog. I’m sure no matter where we reside we have seen days when the sun was hidden in the clouds and  it remained foggy for the entire day, especially in winter.

It is said that London experiences more fog than Dublin. Fog rolls in there about once every two or three years. The Thames River may have a good deal to do with the city having a bit more fog, but believe me, it is nothing like it has been reported to be.
