Will We Have a White Christmas?

18 December 2014, 12:11

When was the last white Christmas you can remember? It will depend on where you live in the country of course. If you live in the Highlands of Scotland you may well see snow more years than not. However if you live somewhere in England the odds are much longer, which could be why more people place bets the moment the mercury starts to drop and the woolly jumpers come out.

Obviously the closer we get to the big day the easier it is to gauge whether there is a chance of snow. However it does help to know what temperature needs to be achieved for it to even be counted as a possibility. Many people believe it needs to drop to freezing or below in order for it to snow, but this isn’t the case. According to the Met Office it merely needs to fall lower than 2 degrees Celsius. This equates to 35.6 Fahrenheit. So it could be just over 1 degree Celsius and if there is precipitation around it will fall as snow.

This means it is a good idea to check the weather forecast to get a look at the temperatures that might be achieved in the run up to Christmas. It can feel pretty cold when it drops to around 4 or 5 degrees Celsius, especially if it is breezy. Yet as we now know it won’t snow at this temperature.

Of course we could end up with a very cold Christmas Eve leading into Christmas Day, with temperatures below those needed for it to snow. This is only half the equation though. If there is no cloud and no moisture in them to fall, it still won’t snow. So you need both elements in place to provide the chance of a white Christmas.

Even then the people betting money on seeing a white Christmas only need one snowflake to fall on a specific weather location (such as the Met Office HQ in London for example) to win their bet on it snowing on Christmas Day. This wouldn’t qualify as a white Christmas for most of us. We won’t be happy unless we wake up on Christmas morning to see a covering of snow, or to see it at least snowing reasonably heavily to give us a covering by the time turkey is served!

As you can see, there are a lot of variables here. If you’ve placed a bet this year it may turn out to be too warm to warrant a payout on a white Christmas. However anything can happen with the great British weather as we all know. This means there is the chance of seeing freak weather and being able to make snow angels on Christmas Day. Well, you never know do you? Happy Christmas.
