2011 the warmest April in Central England

Figure 1

There may well be a warm spell coming later this week, but I’m afraid that even with these high temperatures, April 2018 won’t be a patch on the exceptionally warm April of 2011 (fig 1), which in fact was the warmest since the data series began in 1659 (fig 2) with an anomaly of +3.93°C. It didn’t just sneak past the previous warmest April it smashed past it (fig 2) by over 0.6°C (2007), which in itself was over 0.5°C warmer than the previous warmest April. Is it just me, or do we all have short memories of memorable warm spells?
