Weed pollen will be the main contributor to pollen levels over the coming days, with the highest concentrations expected across much of England, Wales and Northern Ireland.
However, pollen levels are forecast to gradually ease through the weekend and into the start of next week.
Pollen levels are generally low across northern Scotland, including Orkney & Shetland, the Highlands & Eilean Siar and Strathclyde. Moderate weed pollen is expected across Grampian, Central, Tayside & Fife, and Dumfries, Galloway, Lothian & Borders. Elsewhere, high weed pollen levels are forecast across Northern Ireland, northern England, the Midlands, Wales, eastern England, London and the southeast, and southwest England.
Pollen levels fall markedly across most regions on Friday, with low levels expected across Scotland, Northern Ireland, northern England, Wales and the northwest. Moderate weed pollen will persist across the east Midlands, west Midlands, east of England and southwest England, while London and southeast England remain the only region with a high pollen forecast.
Into the weekend, low pollen levels are expected across almost all regions. The exception is southwest England, where weed pollen is forecast to remain at moderate levels.
The pattern changes little on Sunday, with low pollen levels continuing across Scotland, Northern Ireland, northern England, the Midlands, Wales, eastern England and the southeast. southwest England is again expected to see moderate weed pollen.
Low pollen levels are forecast nationwide by the start of next week. This includes all regions of Scotland, Northern Ireland, England and Wales, providing welcome relief for many pollen sufferers after the higher levels experienced earlier in the period.
