Britain is looking forward to another week of glorious weather as bookmakers revealed this spring is now odds-on to be the warmest on record. On what is expected to be another unseasonably warm week, forecasters say temperatures in the South could reach  23C (73F) by Wednesday. People have made the most of the sunny weather this weekend by heading to beaches and parks across the UK, with Brighton particularly busy. The best temperatures at 2pm today were 16.2C (61.2F) at Achnagart in the Scottish Highlands, followed by 14.5C (58.1F) in Plymouth, Devon. Scroll down for video .

Met Office meteorologist Emma Sillitoe said yesterday: 'It is definitely very warm for this time of year as it should be around 12C (54F).'

Yesterday’s top temperature in the UK was 17.6C (63.7F) - observed in Achnagart in the Highlands and Pembrey Sands in Carmarthenshire. But that was still some way off last Wednesday’s 2015 UK high of 25.1C (77.1F) in Kent, making it the warmest April day in the UK for four years. Parts of Britain could face a drought as the Met Office cut its rain forecast following last week's heatwave. The unseasonably high temperatures last week saw highs of more than 25C (77F) in the South East - nearly double the average for this time of year. And forecasters warned that initial figures suggest that so far this month Britain has only seen 35 per cent of the average rainfall for April. The dry spell follows months of below-average rainfall and conditions are not expected to bring significant showers before May's arrival. Met Office meteorologist Emma Sillitoe said: ‘We are over halfway through the month but we've had around a third of the rainfall we get on average. ‘Over the next week temperatures are going to stay above average for most parts of the country, with the high pressure lasting until the weekend.’ Weather data for the year so far shows national rain fall has been significantly lower than average nearly every month. The year got off to a soggy start, with January seeing 20 per cent more rain than average but then 13 per cent less than usual fell in February. Last month the figure was 5 per cent below average. The Environment Agency said: ‘River and groundwater levels across England are healthy.’
