Pollen levels to climb this weekend as sunshine continues over NI

Published 23rd Apr 2026

High levels of pollen are forecast across much of the UK this weekend, as high pressure continues, keeping conditions mostly dry with plenty of fine weather.

According to the Met Office, birch pollen levels increase from moderate to high in Northern Ireland, with a brief spell of very high levels likely.

Some Moderate levels of ash pollen are still possible. Dry, settled conditions and sunshine will promote pollen release, especially inland and in sheltered valleys.

Steven Keates, Deputy Chief Forecaster said: "High pressure will remain broadly in charge of the UK's weather for the remainder of this week and into the weekend. Most places will remain dry with a fair amount of sunshine too."
