All eyes are on the UK's crucial winter weather forecast as the temperatures will affect how households manage their energy bills.
Long-term weather forecasting is notoriously difficult, but forecasters can come up with a broad sense of the weather in the months ahead.
For those trying to reduce their bills this winter, the impact of cold or mild winter will be huge in terms of energy use, said Christopher O'Reilly of the department for meteorology at the University of Reading.

Winter temperatures in the United Kingdom have a significant impact on the demand for gas and electricity, according to him, as per The Guardian.
For example, a 1C temperature anomaly in winter results in a daily average gas demand anomaly of 100 GWh over the winter season.
Based on the UK October gas price cap (10.3p per kWh), this equates to about £1bn for each 1C UK temperature anomaly. The numbers are large, and the stakes are high.
As a result, the latest long-term Met Office forecast will be welcome news for households across the UK. Prof Paul Davies, Met Office fellow (meteorology) and chief meteorologist, forecasts mild late autumn and early winter, with wet and windy weather primarily in the north and west.
However, the impact on energy bills may not last because, as November turns to December, there may be a cold snap with the threat of snow and ice, especially in the north.
Milder conditions, on the other hand, are expected to return in 2023, and Davies believes the chances of a very cold winter similar to 2009-10 are low this winter.
The North Atlantic Oscillation has the greatest impact on European winter weather. Positive phases correspond to windy, mild, and wet weather, while negative phases correspond to still, cold, and dry weather, so we can get an idea of how likely a windy winter is.
Another global factor that could have an impact on the UK this winter is La Nina, which is characterized by a cooling of the ocean in the tropical Pacific, resulting in high pressure in the Atlantic in late autumn and early winter, as well as potential cold snaps in the UK.

WXCharts, an independent forecasting group, predicts a wintry shower over Scotland's Highlands next weekend.
The cold front is expected to hit the mountains on Saturday afternoon and last until early Sunday morning.
According to the Met Office, this weather front will bring heavy rain elsewhere, with much of next week dominated by 'changeable' wet and windy weather, as per The Mirror.
According to Alex Deakin of the Met Office's 10 Day Trend, "what we appear to be left with through next week is a similar pattern to what we've got now, with low-pressure systems mostly to the north and areas of high pressure to the south, and a reasonably active jet stream pushing everything along."
While October is too early for significant snowfall outside of the UK's northern peaks, long-term forecasts released by high-level meteorologists now indicate we may be in for a cold winter.
A rare "long La Nina" weather phenomenon, characterized by large-scale cooling of ocean surface temperatures, may even bring snow flurries next month.
Forecaster Nick Finnis wrote on his Netweather blog this week that the jet stream appears to be diverging further south for November, December, and January, exposing the British Isles to cold "polar air" in his analysis of the official ECMWF long-range forecast released this week.
This would imply that the jet stream and storm track would be diverted further south than usual, increasing the likelihood of colder spells in northern Europe, including the UK, during November, December, and January.
As many people struggle with the rising cost of heating their homes, the predicted cold snap threatens to send energy bills skyrocketing.
