We can already say that it has rained more in these 20 days than during the entire month of June since1991! So far, the accumulated rainfall in June 2026 is 110.6mm, about 53% above the average for the month. 

In the coming days, the rain should let up as a high pressure system brings drier and colder air to the region. But looking ahead, a rainier period is expected at the end of the month.
