Hafnarfjörður, a coastal town within Iceland’s greater capital region, receives around 800 mm (about 31 inches) of rain a year, similar to Reykjavik, given its shared exposure to fast-moving North Atlantic weather systems. Built partly on a lava field, the town’s unusual volcanic terrain doesn’t significantly change its overall rainfall pattern, though it does affect local drainage in some areas. As with the rest of the capital region, wind is often as much a factor in daily weather as rainfall amount. Because Icelandic weather can shift from calm to stormy within hours, radar tracking remains a genuinely practical everyday tool for residents. Iceland’s Meteorological Office operates the national radar network.
