January 2026 Weather Recap: From Arctic Blasts to Atlantic Storms

January 2026 delivered a clear “month of two halves” across the UK. Provisional summaries indicate a cold, dry opening that gave way to a stormy and much wetter second half as Atlantic systems dominated. If you run a home weather station at home, the shift would have been obvious in the pressure trace, rainfall totals, and wind stats.

This recap uses Met Office provisional figures and regional summaries where available, plus reported impacts from named storms through the month.

A Cold Start That Didn't Last

The month began with a cold snap. Observations show Arctic-origin air pushing south during the first week. This brought widespread frost and periods of snow, especially over higher ground in Scotland and northern hills. Reports indicate locally severe overnight minima in sheltered spots, with some Highland sites near -8°C early in the month.

A digital weather station would typically show a classic “cold and dry” signature in this setup. Night-time temperatures fell quickly under clearer skies. Relative humidity often dipped away from coasts, then recovered after sunrise.

The pattern did not hold. By mid-month, the circulation shifted as Atlantic lows began to run in more freely.

When the Atlantic Took Over

From around 10 January, provisional analyses suggest the Atlantic reasserted itself. The jet stream became notably active and frequently aligned towards the British Isles. This supported repeated cyclogenesis upstream and a steady progression of low-pressure systems into the UK.

Named storms were the headline acts. Three systems stood out in reports and regional summaries. They were Storm Goretti, Storm Ingrid, and Storm Chandra.

Storm Goretti was the flagship event. Observations show a deep low with a central pressure near 969 hPa, and reports indicate peak gusts up to 99 mph in exposed locations. Its evolution is consistent with a Shapiro-Keyser structure, with a wrapped warm front and a pronounced bent-back front as the system matured. If you had a barometer at home, the pressure fall and rapid recovery would have been difficult to miss.

Storm Ingrid followed with a different track and timing. Regional summaries indicate a renewed spell of heavy rain and strong winds, with the north and west again favoured for the highest impacts as soils remained wet.

Storm Chandra closed the month with another round of heavy rain. Provisional reporting indicates some locations saw record daily rainfall totals above 100 mm during Chandra’s peak, adding to flooding and surface water issues in the usual west-facing hotspots.

Regional Breakdown: A Country Divided

The UK rarely lines up neatly, and January 2026 was another month where regional exposure mattered. Met Office provisional regional summaries indicate a strong west-to-east split in rainfall and wind impacts.

Cornwall and Southwest England saw repeated bouts of heavy rain and strong coastal winds as systems arrived off the Atlantic. Observations show several intense rainfall days in quick succession, and reports indicate local flooding in the more exposed catchments. A garden weather station would have logged this clearly in accumulated rainfall and repeated gust spikes.

Northern Ireland also stayed on the wet and windy side of the flow. Provisional summaries suggest frequent frontal rainfall, with additional pulses around the named storms. River levels were reported to rise quickly after heavier bands.

Scotland again ran a two-part story. The early cold spell brought snow and frost, then the west shifted to a wetter regime as the storm track became more dominant. Eastern areas were more sheltered at times, consistent with rain-shadow effects in a westerly flow.

Eastern England was comparatively less storm-affected for rainfall totals. The blocking high over Eastern Europe occasionally extended influence far enough west to nudge the storm track and reduce the frequency of heavier rain bands in the east, even when the wider pattern remained unsettled.

Wales sat on the boundary. Western hills and valleys were repeatedly exposed to orographic enhancement in the south-westerly flow, while some inland areas saw more mixed precipitation depending on elevation and timing.

Why Did This Happen?

Provisional synoptic analysis points to a familiar combination. It was an early cold feed, then a strongly forced Atlantic regime.

The opening cold spell aligned with high pressure to the north and northeast, allowing colder air to push south at times. This supported clearer nights and widespread frost.

Later, the key ingredient was a blocking high over Eastern Europe. This feature helped slow and redirect the broader pattern. It did not stop Atlantic lows arriving, but it influenced their preferred track and the persistence of unsettled conditions.

The second ingredient was an active jet stream across the Atlantic. Observations and forecasts through the period indicate a fast, energetic flow that repeatedly supported deepening lows. In events like Goretti, the frontal evolution matched a Shapiro-Keyser cyclone structure, which can be associated with intense winds near the bent-back front as the system occludes.

An anemometer would have shown the practical outcome. Winds freshened repeatedly into strong south-westerlies ahead of fronts, then veered and eased behind them before the next system arrived.

How January 2026 Compared to January 2025

Here's where things get interesting. January 2025 was almost the complete opposite.

Last year was notably drier and colder overall. High pressure dominated much of the month, bringing settled conditions with widespread frost and fog. Rainfall totals were below average across most of the country. It was the sort of January where your hygrometer UK readings would have shown consistently low humidity levels, especially during those crisp, clear days.

January 2026 flipped the script entirely. Where 2025 was settled, 2026 was stormy. Where 2025 was cold and dry, 2026 (after the first week) turned mild and extremely wet. The contrast between consecutive years highlights just how variable UK weather can be.

Temperature-wise, despite the cold start, January 2026 actually ended up averaging slightly milder than 2025 thanks to all that mild Atlantic air that accompanied the storms. Western areas in particular saw some surprisingly warm days between storm systems, with temperatures reaching 12-13°C on occasion.

What Weather Observers Noticed

For anyone keeping local records, January 2026 offered a tidy case study in regime change. Observations show sharper pressure swings once the storm sequence began, with rapid falls ahead of each low and quick rebounds in the clearer slots behind.

A barometer trace would have been the simplest “headline chart” of the month, especially around Storm Goretti’s deepening. Rain gauges in the west needed regular attention, and reports during Storm Chandra indicate record daily totals above 100 mm at some sites.

Wind data from a home weather station often tells the same story in a different language. Gust peaks clustered around frontal passages and tighter pressure gradients, consistent with a vigorous jet-driven storm track.

Humidity stayed high once the Atlantic pattern established. A hygrometer uk reading indoors and out would likely have remained elevated for long periods, particularly in the wettest western regions.

Looking Back, Looking Forward

January 2026 was a neat demonstration of how quickly the UK can flip from continental-style cold to full Atlantic drive. Provisional data suggests the “two halves” split was genuine in both feel and impacts. January 2025, by comparison, is generally described in Met Office monthly reporting as more settled and drier for many areas, with fewer high-impact wind and rain events.

For practical observing, this was the sort of month where your kit earns its keep. A home weather station can capture the shift cleanly in pressure, wind, rainfall, and humidity. A digital weather station makes it easier to spot the timing of frontal passages. An anemometer helps separate “blustery” from genuinely strong gust events. A barometer provides the big-picture pressure story. Even a simple indoor-outdoor sensor can be useful when damp spells linger, especially if you track comfort levels with a hygrometer uk.
