10 July is regarded, especially in Austria, much as Seven Sleepers Day in June is elsewhere, as particularly important for predicting the weather in the weeks ahead.
The traditional saying goes: "If Seven Brothers Day is a rainy day, it will go on raining for another seven weeks." As there is hardly any sign of precipitation anywhere in Europe at the moment, the following proverb is more likely to apply: "If the seven brothers bask in the sun, seven weeks of bliss will follow."
