Last week, people were digging out fans, buying ice lollies, and talking about the heatwave.
A few days later? Rain. Grey skies. Jackets back on.
If you’ve found yourself leaving the house in sunglasses and coming home soaked, you’re not alone. British weather has always been unpredictable, but lately it feels particularly indecisive.
And while the changing forecast is a running joke in the UK, those sudden shifts can affect more than just your plans for the weekend.

Just when you thought summer had arrived in the UK, the rain reminds you where you live.
Why do we feel different when the weather changes?
Most of us have had one of those days where we wake up feeling a bit sluggish, develop a headache halfway through the afternoon, or wonder why we’re suddenly exhausted despite getting a decent night’s sleep.
The weather isn’t always to blame, but it can play a part.
When temperatures jump up and down, our bodies are constantly adjusting. One day you’re trying to stay cool, the next you’re reaching for an extra layer. Add in changing pollen levels, rain, humidity, and disrupted sleep, and it’s easy to feel a little out of sync.
The warm weather trap
The funny thing about warm weather in Britain is that we’re never quite prepared for it.
A couple of sunny days arrive and suddenly everyone is eating lunch outdoors, staying up later, and spending more time in the sun than they normally would.
There’s nothing wrong with that, of course. But it’s also surprisingly easy to become dehydrated or simply run yourself down without realising it.
A mild headache, feeling unusually tired, or struggling to concentrate can sometimes be as simple as not drinking enough water.

If you’ve been sneezing more than usual lately, it might not be a cold — pollen levels could be the culprit.
Is it a cold or just hay fever?
Every year there seems to be a point where people start asking the same question.
“Am I getting ill, or is it just hay fever?”
With pollen levels rising through spring and early summer, symptoms can be surprisingly similar.
Sneezing, watery eyes, headaches, congestion, and tiredness can all make you feel as though you’re coming down with something, when in reality your body is just reacting to what’s floating around in the air.
Don’t underestimate the power of a bad night’s sleep
When warm weather arrives suddenly, sleep is often the first thing to suffer.
A few restless nights can leave you feeling irritable, low on energy, and generally not quite yourself. Then the rain arrives, the temperature drops, and your body is trying to adjust all over again.
It’s not exactly dramatic, but it can leave you feeling a bit off.

A few warm days can be enough to leave you feeling dehydrated without even realising it.
The British solution
There’s probably no way to completely prepare for a week that starts like Spain and ends like November.
But keeping a water bottle nearby, checking pollen levels if you’re prone to allergies, and accepting that you’ll probably need both sunglasses and a waterproof is a good start.
Because if there’s one thing we can rely on, it’s that the forecast will change again tomorrow.
