In Manchester at the moment it is -2 Celcius, there is still snow on the ground and not a blossom to be seen. So, no one’s saying that particular brocho yet.
Golfer, In the southern hemisphere the seasons are not “mixed up”. They are in the same order as the rest of the world. Just, opposite from the northern hemisphere. In South Africa, we said the brocho for blossoms in Av/Ellul. I remember as a child once saying it together with Rav Moshe Sternbuch, on Shabbos Chazon, which happened to be Tisha B’Av.
