Egilsstaðir did not get the 25°C forecasted but just a "mere" 22°C (71.6°F)... and we had 10/11°C (50/52°F) in Reykjavík.
The next few days are still nice in the East and still rather fresh in the West with almost always 5/6°C difference between Egilsstaðir (top) and Reykjavík (bottom).
With such difference in temperature between East and West, there is no point getting a summer house in Spain, Croatia, or any other Mediterranean country... Just head to Egilsstaðir!!!
weather outside: Mostly cloudy, 11°C
