Every autumn, someone asks us the same question: will it be a bad winter? We can’t promise a crystal ball, and neither can the Met Office. But two outlooks in a row — issued a month apart — are now telling a consistent enough story that it’s worth building into your planning, rather than waiting to see what November actually brings.

Why that’s a good reason to book now, not later

A season forecast as “wet and windy, cold risk further out” is harder to plan around reactively than a season that’s simply cold from the start. The safer move is to have cover already arranged rather than watching the outlook update month by month and hoping there’s time to react when it does.
Wet ground sets up ice fast. More standing water and saturated surfaces this autumn means less warning once a cold snap does arrive.
Rounds fill up early regardless of the weather. We build our winter rounds around which sites are already on our books and where they sit relative to our depots and other rounds — arranging cover in good time means a smoother fit into an efficient round, rather than a squeeze once things get busy.

Here’s the detail behind that, straight from the Met Office’s own outlooks.

Two ways the Met Office forecasts, and why we’re using this one

Day to day, we plan our gritting rounds around the Met Office’s Open Site forecasting service — a short-range, postcode-level forecast that tells us what’s actually going to happen this week, which is exactly what you need for a decision like “do we grit tonight.”

For planning further ahead, the Met Office produces something quite different: the UK 3-month Outlook, built specifically for “planners in government and business who make risk-based decisions.” It doesn’t predict the weather on any given day — the Met Office is explicit that it’s “a watching brief only, not used to inform immediate action.”. What it does instead is shift the odds across three bands (say, COLD / NEAR AVERAGE / MILD) away from their normal 20/60/20 split, based on the big global patterns influencing the UK that season. That’s the right tool for deciding when to get your gritting arranged — not for deciding whether to grit next Tuesday.

What the last two outlooks actually say

The Outlook for September–November 2026 gave fairly clear signals: a 40% chance of a warm autumn overall (twice the normal likelihood) against just 5% for cool, and a 30% chance of a wet season (one and a half times normal) against 15% for dry.

The newest one, covering October–December 2026 (issued 28 September), sharpens that picture rather than changing it. Its own summary says:

There is double the normal chance of this period being wet overall
The chance of a mild autumn and early winter is higher than normal
However, there does still remain a chance of impacts from cold weather later in the period
Windy weather is more likely than usual overall

In numbers: a 40% chance of a wet season (double normal) against 10% for dry, a 30% chance of mild (one and a half times normal) against 15% for cold, and a 25% chance of windy (also above normal) against 15% for calm.

The El Niño behind it

Both outlooks point to the same driver: an exceptionally strong El Niño event. The October–December Outlook describes it as “an already unprecedented El Niño event, with further strengthening expected over the coming weeks,” likely to persist until at least early 2027. In plain terms, El Niño is a shift in Pacific Ocean temperatures that ripples out to affect weather patterns worldwide, and one of its more reliable effects on the UK is to load the dice towards wetter, stormier conditions here and across northwest Europe during late autumn and early winter. This year’s event is strong enough, and the different forecasting models agree with each other closely enough, that the Met Office says it has “a somewhat greater degree of confidence” in this outlook than usual.

So does “mild and wet” mean gritting can wait? Not quite

It’s tempting to read those figures and assume the cold’s been cancelled. Worth being careful here, because the Met Office itself isn’t saying that. Both outlooks are explicit that a lower-than-normal chance of a cold season doesn’t rule out real cold weather within it — the October–December Outlook says plainly that “periods of impactful cold weather remain possible later in the period,” even while the overall risk of prolonged, widespread frost, ice or snowfall this side of Christmas is reduced compared with a typical year.

That’s a genuinely useful distinction for planning. The overall odds favour a wet, mild, often windy October, November and December — but not a fully mild one, and the outlook’s own language leaves the door open a little wider the further into the period you go. The next Outlook, due 26 October and covering November–January, will start to say more about the turn of the year; and it’s the deeper winter months — January, February, into March — where El Niño’s grip tends to loosen and colder interludes become more likely, a pattern the Met Office nods to without yet quantifying this far ahead.

There’s a practical angle too: a wetter-than-average autumn, on the back of a dry summer in many areas, means more moisture sitting in the ground and on surfaces heading into winter — exactly the kind of surface that ices up fastest and with the least warning once temperatures do drop, whenever in the season that turns out to be.

We’ll be keeping an eye on this ourselves, too. The Met Office issues a fresh 3-month Outlook every month through the winter, so we’ll come back and update this post each time a new one lands — including the November–January Outlook due 26 October, and the one after that covering December–February — so it keeps reflecting the latest picture right through the gritting season.

What forward planning actually looks like

It’s genuinely simple. Send us a marked-up Google Earth image of your site, and we’ll turn around a bespoke, no-obligation quote — often the same day — with your choice of cost-per-visit, fixed annual cost, or a mix of both. Get that in place now, while the outlook is still unsettled rather than urgent, and whichever way this winter plays out, you’re covered rather than scrambling.

The bottom line

Nobody — including the Met Office — can tell you exactly which week the ice will bite. But two consecutive outlooks now agree: a wet, mild, often windy autumn and early winter, driven by one of the strongest El Niño events on record, with cold impacts still possible later in the period even so. That’s about as useful a steer as forward planning ever gets. Get your gritting arranged while the phones are quiet, not when they’re not.
