I want to change order of this facet_wrap (see below).

Instead of 'Midtre Ost', 'Osterbotn', 'Porsangnes East' (from left to right), I would like 'Porsanges East, Midtre Ost, Osterbotn'
Is there a way to do this without modifying my data frame?
labels <- c('por' = "Porsangnes East", 'mid' = "Midtre Ost", 'ost' = "Osterbotn")
ggplot(data, aes(x = depth, y = temp, colour = month))+
theme_bw() +
geom_line(size=1, linetype=1) +
labs(x = "Depth/ m", y = "Temperature/ °C", colour = "Month") +
scale_colour_manual(values = c("#FF6666", "#FFCC00", "#66CCFF", "#00CC33"), labels=c("August", "May", "November", "October")) +
geom_point(size=0)+
scale_x_reverse()+
scale_y_continuous(position="right")+
coord_flip()+
facet_wrap(vars(location), labeller = as_labeller(labels))
