In early November, the UK is experiencing an unusually mild period, with temperatures significantly above the seasonal average. However, the Met Office's latest 10-day outlook indicates this calm warmth will soon transition into more unsettled and variable conditions as the new working week begins.
The current mild weather is driven by a strongly wavy jet stream across the Atlantic Ocean. This causes a series of dips and troughs, including one extending down toward Iberia.
Over the coming days, this trough is expected to deepen, anchoring low pressure to the south and moving it northward toward the UK as the weekend approaches.
As the weekend unfolds, another dip in the jet stream will bring a wider trough over the Atlantic. This weakening yet amplifying jet stream pattern plays a critical role in creating slow-moving weather systems next week, pitting low pressure to the west against high pressure to the east of the UK.
Temperatures overnight on Bonfire Night 2025 only dropped to 14°C.
This set a new record for mild conditions during the event.
Summary: Early November’s mild UK weather is set to end as a wavy jet stream brings unsettled conditions, with temperatures notably above average for the season.
