Sunshine & warm temperatures forecast this weekend over Northern Ireland
Last updated 7th Jul 2025
Summer has well and truly arrived this week across the UK, with forecasters predicting mid-20°C weather in the upcoming days.
High pressure from the Atlantic will gradually move in this week, bringing with it warmer temperatures.
Deputy Chief Meteorologist Dan Holley explains: “We’ll see temperatures build day-on-day, with the potential for hot conditions to become quite widespread by the end of the week and into the weekend.
“High temperatures are likely to persist into the weekend, especially away from coasts with onshore winds, reaching the low 30s in portions of England and Wales, and accompanied by rising humidity and warmer nights.
“This heatwave is likely to last longer than previous ones so far this summer, and affect a wider area, with the focus for some of the highest temperatures displaced across more central and western areas at times. In addition, pollen and UV levels will also be very high in some areas.”
