No wonder we were getting messages in Europe that it was cold in Adelaide this June – it was the driest June since 2006, so it was probably the lack of humidity which made it seem so cold, even though temperatures were close to average. Rainfall for Adelaide in June was only 15 mm, compared to the long term average of 80 mm.
Interestingly, at the same time, it was the coldest and wettest June in Denmark for many years, leaving the Danes asking ‘where is our summer?’ The strawberry season was very poor, as there had not been enough sun to ripen the fruit, and the available berries were smaller and often mis-shapen.
Back in Adelaide again for July, it seems that the seasons have got confused. Some plants think it is autumn, still flaunting their autumn colours, while standing next to golden wattles in full spring flower. At the same time, almond blossom is already well-developed, much too early for the annual almond blossom festival at the end of July. The usual green grass cover of winter is definitely lacking in country paddocks.
The weather map has three major high pressure systems sitting right across the southern half of Australia, pushing the cold fronts further south so that the rain is missing the mainland. Adelaide’s rainfall over the past 12 months has been highly variable, with no rain in December or February, 10% in March but double the average volume in January. With El Nin҄o already confirmed, it is concerning that a winter rainfall deficit may be developing, with serious implications for Adelaide’s water supply in the coming months.
