Marek Ratajczak, a forecaster at the Norwegian Meteorological Institute, told The Local that July was shaping up to be “quite usual for the Norwegian climate”, with a few days of sunshine, followed by a few days of colder weather, and dry days interspersed with rainy days. 

“What the forecasts show is that there is a higher probability of low pressure systems in the Scandinavian region, which means that the weather will probably be changing a bit, like it has been doing in now in June. So we will have some cold days and some warm days.” 

On the plus side, he said that the forecasts suggested this July would be slightly warmer than average, but it could also be rainy. 

“It depends where the low pressure is located. If it’s located closer to the UK, then it has a higher chance of bringing in hot air from the south and southeast,” he said.

“The low pressure may also increase the chance of at least some periods of precipitation. You can expect a bit of usual Norwegian weather, when you have some days of sunshine and some days of rain, but there are no signals suggesting that it’s going to be unusually wet.”

Yr, the weather forecaster jointly run by the institute and NRK, only issues 21-day forecasts, but already in the days leading up to July 21st, it’s clear that some rain is expected.
