Meteorologist Trausti Jónsson believes temperatures could possibly reach 20°C (68° F) tomorrow.
On his blog, he points out that very warm air is over the country right now and will be for the most of tomorrow, Saturday. Should the temperature reach 20° C, that would be a record.
The record for October 16 dates back to 1934, when the thermometer registered 18.2° C (65° F) in Teigarhorn, East Iceland. The October 17 record is 17.0° C (63° F) from Hólar, Hornafjörður, South Iceland, in 1978.
“With luck, those records could be broken, but of course that’s not certain, and we won’t be that disappointed if they don’t,” Trausti writes in his blog.
