Rivers and streams have been shrinking and even drying up entirely following several weeks with little to no rainfall in Iceland. In Stykkishólmur, West Iceland, where measurements stretch back to 1857, last July was the second-driest one on record. In West and Southwest Iceland, rainfall has been less than 10% of the average for July and early August, according to Meteorologist Einar Sveinbjörnsson.
“Around July 20 it caught my attention that for example east of Lómagnúpur mountain [in Southeast Iceland] there were already numerous dry streambeds,” Einar wrote yesterday on his Facebook page, where he maintains a weather blog. “It was impossible to find usable drinking water. That was about four weeks ago. Since then, there has been almost no rain in that area.”
While Iceland experienced a rather wet spring, the weather shifted in July across most of the country, with Stykkishólmur reporting just 4.7 mm of rainfall that month and only 0.5 mm since. In Höfn, Southeast Iceland, rainfall measured 11.6 mm, a record low (although notably, the town’s records do not go as far back as those in Stykkishólmur).
Einar observes that the dry spell has affected water levels in many rivers across the country, even glacial rivers fed by meltwater during the summer. Norðurá river at Stekkur and Fossá river in Breiðafjörður measure at just 1% of their average flow rates for this time of year.
According to Einar, the North Atlantic fronts that usually unload their rain over Iceland have instead moved over the British Isles and Northern Europe, where weather has been unseasonably wet. Ireland has been experiencing record rainfall and downpours have caused floods in Norway and elsewhere.
