1. Check the long-range forecast.
The long-range forecast can give you a general idea of what the weather will be like in Ireland over the Christmas period. If you’re checking the forecast in early December, look for a prediction of cold, clear weather in the lead-up to Christmas.2. Monitor the jet stream.
The jet stream is a fast-moving band of air that flows from west to east across the Atlantic Ocean. When the jet stream is positioned over Ireland, it can bring mild, wet weather. However, when the jet stream is positioned further north, it can allow cold air from the Arctic to reach Ireland, bringing snow.3. Observe the wind direction.
The wind direction can also give you an indication of the weather to come. If the wind is blowing from the east or northeast, it is more likely to bring cold, dry weather. On the other hand, if the wind is blowing from the southwest or west, it is more likely to bring mild, wet weather.4. Look at the leaves on the trees.
If the leaves on the trees are still green in early December, it is a sign that the weather has been mild and there is less chance of snow. However, if the leaves have fallen off the trees, it is a sign that the weather has been cold and there is a greater chance of snow.5. Listen to the folklore.
There are many old wives’ tales about the weather in Ireland. One such tale is that if there is a lot of holly berries in the autumn, it is a sign that there will be a hard winter. Another tale is that if the first snow falls on a Monday, it will be a long, cold winter.Of course, there is no guarantee that any of these methods will accurately predict the weather on Christmas Day. However, they can give you a general idea of what to expect and help you to increase your chances of seeing snow on the big day.
So, if you’re dreaming of a white Christmas in Ireland, start checking the forecast and monitoring the jet stream. And who knows, you may just be lucky enough to see snow falling on Christmas morning.
