Parts of the UK are set for one more taste of summer this week, as temperatures are predicted to reach around 26°C in the south-east, including London, Brighton, and Canterbury, before cooler, more typically autumnal conditions return.
As for the rest of England, residents are expected to see highs of 17-20°C, with 19°C in Cardiff, 17°C in Belfast, and cooler conditions further north in Scotland. The result is a brief window for anyone reluctant to pack away their summer wardrobe just yet.
Not Quite a Heatwave, But a Warm Spell
Let's be a bit more precise here. This isn't an official heatwave. The Met Office has previously pushed back on media coverage that overstates similar late-season warm spells, and this one falls into the same category: a genuine, welcome rise in temperature, but a short and localised one instead of a sustained heatwave event.
That does not make the warmer weather any less useful from a wardrobe perspective. A few mild days can be enough to bring some lighter pieces back into rotation before the season properly shifts.
What To Pull Out
That still leaves a window worth dressing for. Linen trousers, lightweight sundresses, and sandals can all fairly reasonably come back out of storage for a few days, particularly for anyone in the warmer south-east pockets of the forecast.
A sleeveless midi dress or a linen shirt worn open over a vest are both easy options that don't require digging through packed-away boxes. The key is choosing pieces that can easily accommodate cooler mornings and evenings.
Make Summer Pieces Feel More Seasonal
The trick to avoiding a 'didn't get the memo' look is to anchor summer pieces with one autumnal element. A sundress worn with ankle boots instead of sandals reads as a deliberate transitional outfit rather than a rerun of August.
For something a bit more daring, draping a lightweight jacket, even one that stays firmly off the shoulders in the heat, over a summer top signals intent and gives you something to actually put on once temperatures drop again later in the day or week.
Accessories are the easiest lever to pull. Swapping a straw bag for a leather one, or adding a scarf you're not actually wearing for warmth, nudges a summer outfit toward autumn without requiring a full outfit change.
Let a Blazer Do the Heavy Lifting
If temperatures do dip earlier than expected on any given day, a blazer is the single most useful piece to keep nearby.
Worn over a strappy top, a bodysuit, or even a summer dress, it adds enough structure to feel autumn-appropriate while leaving the lighter piece underneath free to come back into its own if the warmth holds.
It's a far more versatile option than a heavy knit, which risks overheating if the forecast runs warmer than expected.
Reach for Colour, Not Just Layers
For anyone wanting to ease into the season's palette without fully committing, small accessories are a low-risk way in.
This autumn season's expected colours, per InStyle, lean towards earthy browns, clay reds, sage green, and butter yellow, all of which work well as a bag, belt, or pair of shoes against pale summer clothing, without requiring a full seasonal wardrobe change. A brown bag with a pale dress, for example, can instantly make the combination feel more seasonal without adding another layer.
Enjoy It While It Lasts
The UK's transition into autumn rarely happens in a straight line. The forecast points to changeable conditions, with drier and more settled spells possible in the south and east alongside rain and stronger winds elsewhere. Temperatures are expected to remain slightly above average overall in the near-term outlook, although cooler spells are still possible.
So there is no need to pack away every summer staple just yet. Keep the linen, lighter dresses and sandals within reach, but pair them with transitional pieces. That way, you can make the most of the warmer spell without being caught out when autumn decides to make its return.
