UK and Ireland storm claims, October 2026: Austen and Boelo in four days

Two storms, two tracks

Austen, named by the Met Office, passed to the south and brought wet and windy weather, especially to the south and east of Ireland, on 22 and 23 October [3]. Boelo, also named by the Met Office, passed to the north and brought wet and windy weather, especially to the north and west, on 24 and 25 October [3]. A further deep depression kept conditions unsettled on 26 and 27 October before the month ended quieter [3]. Northern Ireland is a UK jurisdiction for insurance and for Met Office warnings, and it sat on Boelo's northern track [2].

The Met Office's naming advice for Boelo pointed to Northern Ireland, Scotland and parts of northern England, with possible gusts of 70 to 80 mph on exposed coasts and high ground and 50 to 60 mph more widely, after Austen had already been warned for the south of England and Wales [2]. Those were forecast impacts at the time the storm was named, not a post-event damage survey. The official measurements below are from Met Éireann's station network.

What the official measurements show

Ireland's national mean temperature in October was 11.41 °C, 0.62 °C above the 1991 to 2020 average, the sixth consecutive milder-than-average October and the ninth consecutive milder-than-average month from February [3]. The claims point is the rain and the wind, not the temperature.

Rainfall was above average in most places. Monthly totals ranged from 83.4 mm at Oak Park, County Carlow (90% of average) to 242.1 mm at Newport, County Mayo (157% of average, its wettest October since 2021) [3]. The highest daily rainfall was 43.2 mm (adverse for insurers) at Roches Point, County Cork, on 22 October during Austen [3]. Very wet days, meaning 10 mm or more, ranged from 2 at a few stations to 11 at Newport [3].

The wind was the sharper Boelo signature. Gales were reported on 13 days in the month. Strong gales were reported on 14, 20, 23, 24, 25 and 27 October, including during both named storms [3]. Mean winds reached storm force on 24 October at three stations and on 25 October at two stations, all during Boelo: Mace Head, Malin Head and Finner on the Saturday, and Malin Head and Finner on the Sunday [3]. The highest 10-minute mean wind speed of the month was 56 knots (adverse for insurers) (104 km/h) at Malin Head on 24 October [3].

That pattern, a southern storm followed immediately by a northern one, is a capacity problem as much as a weather problem. Adjusters, contractors and temporary repair labour cannot be in Cornwall and Donegal on consecutive days without a plan that treats the two tracks as two events.

The property cost backdrop is already tight

Even before any storm claims are settled, official rebuild-related prices were rising and some property insurance prices were falling. The Department for Business, Innovation, Science and Trade's construction material price index for "All Work" rose 7.2% (adverse for insurers) in the year to September, and 0.6% (adverse for insurers) on the month. Other new work rose 8.5% (adverse for insurers), repair and maintenance 6.2% (adverse for insurers), and new housing 5.4% (adverse for insurers) [4]. The figures were published on 4 November, covering September, and they are the official UK material-price series.

Over the same year, the ONS house contents insurance CPI fell 9.5% [5]. Materials for maintenance and repair of the dwelling, a narrower CPI component, rose 3.6% [5]. The 7.2% "All Work" index is the better rebuild-cost reference for commercial and domestic property. A book that last updated sums insured on 2025 material-price trends will be short against a 7.2% rise, and shorter still if the insurance price index is falling.

No official Flood Re, Environment Agency or ABI insured-loss total for Austen or Boelo is included here, because none had been published as an official figure for these two storms. Weather severity should not be translated into an invented loss.

The rest of the named-storm list is still unused

The 2026 to 2027 western-group name list, issued jointly by the Met Office, Met Éireann and KNMI, runs from Austen to Wende [1][3]. Only Austen and Boelo had been used by the end of October. Chloe through Wende remain available. The season for named storms in this list runs from early September to late August [1]. A quiet start to the name list is not a forecast of a quiet winter.

What this means for underwriting and claims

Underwriting. Treat Northern Ireland, Scotland and the western seaboard as the Boelo track, and southern England, Wales and the south and east of Ireland as the Austen track, rather than applying a single "October storm" relativity. On property, check sums insured against the 7.2% (adverse for insurers) official material-price rise before giving credit to a falling contents-insurance price index.

Claims. The operational test is whether motor, property and commercial property teams can open two weather events four days apart, on opposite ends of the islands, without the second one sitting in the same queue. Glass, trees, outbuildings and temporary works will show up first. Flood files will take longer, and they should not be reserved as if they were wind-only.
