North West Wales is set for a weekend of two contrasting halves before a much hotter spell arrives early next week, according to the latest forecast briefing.
Saturday is expected to bring a damp and fresher start across western parts of the region, with cloud cover dominating and scattered light showers moving through at times. Temperatures will remain relatively modest for the time of year, holding at around 19°C, with conditions feeling cooler under persistent cloud and occasional rainfall.
In contrast, Sunday is forecast to see a rapid improvement as high pressure builds in, bringing a marked change in conditions. Forecasters expect prolonged sunny spells to develop across the region, with temperatures climbing noticeably. Coastal areas are expected to reach around 24°C, while inland parts of North West Wales could see highs of 25°C, making for what could be a popular day for beaches and outdoor activities.
Attention then turns to the start of next week, where forecasters are warning of a significant surge in temperatures. Monday, June 22, is currently expected to bring the peak of the hot spell, with temperatures forecast to rise to at least 28°C or 29°C across North West Wales.
Latest Met Office updates suggest a sustained period of warmth, with at least six consecutive days where temperatures are expected to exceed 25°C. On that basis, it is anticipated the region could officially enter heatwave conditions by Tuesday evening, depending on how forecasts evolve.
Some longer-range model outputs go further still, suggesting isolated hotspots could reach as high as 32°C later in the week. There is also speculation among forecasters that Wales’ June temperature record could come under threat if the most extreme scenarios were to verify.
With heat and humidity expected to intensify, local authorities and emergency services are urging residents and visitors to take precautions. Beachgoers are being reminded of the dangers of cold-water shock, even in warm weather, and to take care when entering the sea.
Health advice also stresses the importance of sun safety during prolonged hot spells, including avoiding direct sunlight during peak afternoon hours, staying well hydrated, and using high-factor sunscreen as temperatures rise sharply across the region.
