⚡ Quick Answer
As of 8 May 2026 the Met Office shows all UK pollen species at LOW. The calm doesn’t lasts long — the main grass pollen season is days away, with peak grass counts forecast for early to mid-June. A wet winter has set up a vigorous grass crop, so 2026 is being called a high-pollen summer. If grass is your trigger, start a daily antihistamine and a steroid nasal spray this week.
The Met Office pollen forecast published on 8 May 2026 puts every monitored species across the UK at LOW. That sounds reassuring until you remember the calendar: grass season is days away, and grass causes about 90 per cent of UK hay fever cases. This piece pulls together where the count actually is right now, what the rest of May, June and July look like on current forecasts, why 2026 is being called a heavier-than-usual year, and the practical things to do this week if you react to grass. Sources are named throughout — Met Office, Allergy UK, NICE — so you can read further if you want.
Where the UK pollen count actually is in early May 2026
🟢 MET OFFICE STATUS — 8 MAY 2026
All UK pollen species: LOW — but grass season days away.
The current picture is straightforward, according to the Met Office data sheet last updated on 8 May. All species are LOW UK-wide. Tree pollen sufferers are likely past the worst — birch, the big hitter, peaks in late April, and that peak is now passing.
A few signals are flashing for grass-allergy sufferers. Some early-season grass pollen is starting to register at monitoring stations. Tree pollen was reported moderate in the West Midlands. Specific grasses like meadow foxtail, lawn grass and sweet vernal grass have started flowering. The data behind those headlines comes from the National Pollen and Aerobiology Research Unit at the University of Worcester, which runs the network of UK monitoring stations the Met Office relies on.
The headline matters less than what it means: the season is turning, even if the count says LOW. This week is your last clear-air rehearsal.
What May, June and July 2026 are forecast to look like
The next few months are being shaped by one big driver — the wet winter. High soil moisture has set up a particularly vigorous grass crop. If May stays mild and damp, as it has been so far, grass growth will be lush, and that translates directly into pollen.
The forecast pattern: main grass season starting in earnest from mid-May, ramping fast through late May into early June. Grass pollen drives roughly ninety per cent of UK hay fever cases, so this is the bit that matters. Peak grass counts are forecast for early to mid-June, with a smaller second peak around mid-July. After that, weed pollens — nettle, dock, mugwort — pick up the baton from late June through September.
🌱 May 2026 Grass season starts mid-month. Counts begin climbing quickly from the third week. | ☀️ June 2026 Peak grass pollen, early to mid-June. Worst symptom weeks for most sufferers. | 🌾 July 2026 Smaller second peak mid-month, weeds rising as grass fades. |
There’s another piece of context. The alder spike yanked the season forward in late February, when a sudden warm spell pushed alder pollen to “very high” across southern England. Tree-allergy sufferers in the south have already had a tough one. The combination of an early start and a primed grass crop is what has weather and allergy desks calling 2026 a long, intense season. As Allergy UK reports in its weekly updates, the trajectory looks straightforward — and slightly grim — for grass sufferers.
Why 2026 is being called a high-pollen year
Three things stack up. The wet winter primed a vigorous grass crop. The mild spring is firing that growth. And the broader, well-documented climate trend is lengthening UK pollen seasons year on year — earlier starts, later finishes, more bad weeks in the middle.
Add the 2026 alder spike — pollen pulled forward by weeks — and you get a season that doesn’t look like an outlier so much as a prototype. The pollen calendar people learned in childhood is shifting.
There’s an air quality angle too. High pollen plus high pollution amplifies symptoms — irritated airways respond worse to allergens. On bad days, pair the Met Office pollen forecast with the DEFRA air quality forecast and treat them as a combined risk score. None of this is cause for panic, but it is reason to take preparation seriously rather than wait for symptoms to remind you.
🔬 Three reasons 2026 is hitting harder
Wet winter, mild spring, lengthening seasons
The combination of a saturated winter, a growing spring and year-on-year climate shifts is pushing UK pollen seasons longer and harder. Add this year’s early alder spike and you get a template for what future summers may look like for allergy sufferers.
- → Wet winter primed a vigorous grass crop
- → Mild spring is firing growth
- → Climate trend lengthens UK pollen seasons year on year
What you should do this week if grass pollen is your trigger
Honestly, if grass is your usual problem, treating this week as preparation rather than a holiday is the smart move. There are five practical moves, in order of impact:
Start a daily non-drowsy antihistamine
Cetirizine, loratadine and fexofenadine are all available over the counter, all once daily, all far less sedating than older Piriton-style options. Start today so the drug is fully on board before counts climb.
Start an OTC steroid nasal spray TODAY
NHS guidance is to start two to three weeks before your trigger pollen season because fluticasone, mometasone or beclometasone take 1-2 weeks of daily use to bed in. If you’ve been writing off nasal sprays as useless, that may be a timing issue rather than a product issue.
Add eye drops if eyes are involved
Sodium cromoglicate or olopatadine drops help if itchy, watery eyes are part of your pattern. Use them alongside your antihistamine, not instead of it.
Use the free physical barriers
A smear of petroleum jelly around the nostrils traps pollen, wraparound sunglasses cut eye exposure, and a quick shower and change when you come in pulls pollen out of your home before it lands on pillows and sofas. Shut windows during the 5-10am and 5-10pm pollen peaks, and dry laundry indoors on high-count days.
Book a free NHS Pharmacy First consultation if you’re stuck
The pharmacist can match products to your symptoms and refer you to a GP if needed. For severe grass-pollen sufferers, ask about the SLIT tablet pathway — sublingual immunotherapy — now NICE-recommended for NHS use.
Frequently Asked Questions
Is the UK pollen count high right now in May 2026?
No. The Met Office forecast published on 8 May 2026 puts all species at LOW UK-wide. Some early-season grass pollen is starting to register at monitoring stations, which signals the main grass season is imminent. Treat this week as your final prep window rather than a sign that the season is mild.
When is the worst week for grass pollen forecast in 2026?
The Met Office and Allergy UK forecasts both point to peak grass pollen in early to mid-June 2026, with a smaller secondary peak around mid-July. The exact peak depends on weather between now and then — a hot dry week in early June is when symptoms tend to be worst.
Pollen forecast for my area — where to find it.
The free Met Office pollen forecast at metoffice.gov.uk/pollen gives a five-day forecast broken down by UK region and pollen type, updated daily. Allergy UK and the National Pollen and Aerobiology Research Unit at the University of Worcester also publish updates throughout the season.
Why has 2026 been a bad pollen year already?
A sudden warm spell in late February sent alder pollen to “very high” across southern England, pulling the start of the season forward by weeks. The wet winter has also primed a vigorous grass crop. The combination sets up a long, intense overall season rather than a few isolated bad weeks.
When should I start hay fever tablets in May 2026?
If you react to grass pollen, this week — first half of May 2026. The NHS also recommends starting a steroid nasal spray two to three weeks before your trigger season begins, which for grass-allergy sufferers is also now. Tablets and spray together, taken daily, beat single-product treatment for almost everyone.
The Met Office position on 8 May 2026 is low pollen across the UK. Treat that as the final calm before the grass surge. Worth saying: low pollen on the 8th does not mean low pollen on the 18th — the gap is small. The main grass season starts mid-May, peak counts are forecast for early to mid-June, and the wet winter has set the stage for a heavier-than-usual summer. Bookmark metoffice.gov.uk/pollen, start your antihistamine and nasal spray today, and book a free NHS Pharmacy First consultation if you are not sure which products to pick.
