The warmer climate North Wales has been experiencing recently does not necessarily mean there won’t be a white Christmas this year, according to experts in the field at Bangor University. It’s time to check out our holiday parks in North Wales and have a Christmas you won’t forget, white or otherwise! Professor Tom Rippeth of the University’s School of Ocean Sciences points out that the weather patterns with less than two weeks to go until Christmas day itself match those in December 2010 – when the region was last covered in snow. He thinks the jet stream, which is the ultimate dictator on the United Kingdom’s weather, could change course and bring in arctic weather in time for Father Christmas’s arrival. He made it clear that the chances of a white Christmas are well within reach for North Wales, and a lot more likely than most people think. The UK experiences variable weather due to where it sits at the interface between cold polar and warm temperature air masses. To some extent, this makes predicting long-term weather nearly impossible in the UK, due to the erratic nature of weather systems. Professor Rippeth said: “The extent to which Britain feels the effect of these sharply contrasting air masses depends on the position of a high-altitude wind, the jet stream. Over the past few winters the jet stream has been relatively straight, pushing storms across the Atlantic with very mild winter and some catastrophic storms and flooding as a resulting.” However, this year could be different. The jet stream is looking highly uncertain, taking much more of a meandering path, moving to the south, then the north, which helps to explain the warmer, wetter and windier conditions experienced last week. There is every chance that the jet stream could drift back south before Christmas, bringing back cold Arctic air with the potential to result in a white Christmas. Geographically, North Wales is vulnerable to extremes in the winter, be it hot or cold. The south westerly winds tend to be warmer and this is amplified as the winds blow the temperature air over the Cambrian Mountains and Snowdonia, creating the ‘Fohn’ wind effect. The highest winter temperatures on record are located at Aber, near Bangor, in January 1958 and 1971. The climate reached a remarkable 18.3 degrees, which surprisingly was nearly reached on Christmas eve last year! So whether it’s a white Christmas you’re after or a holiday in the sun, North Wales has the potential to provide both! Luckily we can guarantee a good time in this region come snow or shine!
