The Met Office has warned of rising pollen levels in a message to hay fever sufferers.
Forecasters have said milder weather is on the way for Easter, with highs of 19C hitting England by midweek. Similar temperatures are forecast for Easter weekend, with the Met Office saying dry and sunny conditions are expected.
Meteorologist Steven Keates said: "The further south and east you are, the better chance of seeing predominantly dry conditions into the Easter weekend. Probably quite pleasant actually in the sunshine, with temperatures probably on the warmer side for the time of year. So you're probably looking at mid to perhaps upper teens.
