Probably April. It's when the (Southern Hemisphere) summer starts to disappear and it starts getting cold, meaning you have the longest wait until it can be summer again. Truly the Monday of months. Australia doesn't even get that cold. It'll be like 19*C during the day, but it'll be windy, and sometimes it rains, so everyone loses their tans </3
February, for the cold weather and the fact literally nothing happens in it, followed by May because of the exams.
January is bearable because of New Year's Day, family birthday's, and mine and my boo's anniversary, and the fact I have the majority of it off uni. March is okay because it's the lead up to my birthday in early April.
