Cold April, warm June/July, cold September, mild October, cold November - December.

Mmm…I'd love that pattern! Indian Summer with Feb the hottest month…a rare jewel these days.

My prediction is that winter will begin mild, but February is going to be a pain in the ass, 2015-style. Spring and summer will be average to slightly warmer, until August rolls around and is a complete dud of a summer month; it should also be dry the whole time, with July getting almost no rainfall other than the big storm on the 14th. (That's a 2010 reference. )

My updated 2021 prediction St. Middleway Yahya Sinwar



January: the month continues as it has done, with below average temperatures and barely any sun. The month takes the title of cloudiest January on record.
February: continues where January left off. A heavy snow event in the first week brings 15cm to London, but the skies remain mostly grey. When the sky does clear, minima crash to -7c.
March: yet more of the same; cold both day and night with frequent rain and barely any sun or signs of spring.
April: no sun recorded for the first 15 days of the month, accompanied by rainfall and cool temps. The 2nd half brings almost unbroken sunshine with temperatures frequently around 20c.
May: mostly warm, dry with partly cloudy skies. A brief heatwave late in the month produces the first 30c in May since 2005.
June: continues where May left off; mostly sunny skies and temps above 30c in the first few days. The 2nd half of the month is frequently cloudy and cool.
July: A mix of partly and mostly cloudy skies and average temperatures. A plume event mid-month peaks at 35c, but the end of the month is cool, cloudy and dry.
August: very cool, cloudy and dry for the first 3 weeks. The final week is warm with unbroken sunshine, and produces the first above average day of the month.
September: continues warm and sunny as August left off. A 2nd plume brings 30c and some thunderstorms, but the month closes mostly fine and settled.
October: the UK is repeatedly battered by the remains of Atlantic hurricanes. The month is characterised by almost non-stop rainfall and cloud, becoming the wettest month ever recorded.
November: another very mild, wet and cloudy month.
December: frequent winter storms bring plenty of rain, but also allow for the sun to appear in between. A mild and wet month with near average sunshine.

St. Middleway brave going for a sunny June and July!  Your December looks a bit crazy as well with the mean and high being the same.

Summer has been much warmer than I would have expected with both June and July having an average max 4C above normal. Looks to continue into August.
