90 A Rocha Portugal Observatory Report 2009-2010 Rainfall 2010 was the wettest year since 2003. The total rainfall for the year was 273mm higher in 2010 than in 2009 and was 336 mm (37.8%) higher than the yearly average for 2003-2009 which is 553 mm per year (Figure 3). The higher total rainfall was largely due to the very wet months of December, January and February. Figure 6 Monthly rainfall for 2010 and average rainfall for each month from 2003-2009. To show variation across different years (2003-2009) error bars are plotted which represent one standard error.
