Temperatures were expected to reach high teens on Sunday, with an even higher probability in the south as Good Friday was the hottest day of the year so far, with 23.4 degrees Celsius recorded at St James’s Park in London – warmer than Ibiza. However, cloudy skies were expected in the west on Sunday, with rainfall across Northern Ireland and western Scotland slowly extending eastward in a week that the UK Meteorological Agency said it would return to more normal weather in April, when the average temperature is about 12 C. He predicts that temperatures will start to drop from Easter Monday with light rain and clouds during the week. Marco Petagna, a senior meteorologist at the Met Office, said the rain would push from the west during the night, which would “weaken” as it progressed, so the east could remain dry. “The idea is for temperatures to drop gradually every day for the next few days across the UK,” he said. “The further south and southeast you go the more likely you are to stay well again, but [it will be] slightly cooler [on Monday] at 19 in the southeast, low to middle adolescence elsewhere. “ Pollen levels – which were high in most parts of the country, causing misery for people with allergic rhinitis – will begin to decline in many areas from Monday onwards, and Petagna said Easter Monday may be the last of in dry, bright weather for the week. which has seen moderate levels of ultraviolet radiation with “the sun as strong now as August”. He said: “There may be some rain on Tuesday and Wednesday, especially in the south of the United Kingdom. And then the second half of the week is when an east wind blows, mostly with clouds coming in from the east with a little rain, but also very relatively dry weather. “But the trend is definitely for temperatures to drop a bit, so we will return to low local averages by Thursday.” The warm weather on the weekend combined with the first unrestricted Easter for two years meant many people headed to the coast, with Bournemouth attracting some of the largest crowds of the year and Cornwall’s offshore car parks also full of holidaymakers. People returning from weekend breaks have been advised by the RAC to either travel before 10:30 or after 18:30 on Easter Monday to avoid queues.
