The only problem is that I want the data series to plot one on top of the oth

Answer 1

If you want to plot both years in the same plot above each other then use dayMo as your x values (they don't have to be date object).

df$dayMo<-c("06-01", "07-01","08-01","09-01","06-01", "07-01","08-01","09-01")
ggplot(df, aes(dayMo, temp, color=year))+
  geom_point()
