Glenside is situated in a valley. The city is surrounded by hills and mountains to the north and west. These natural barriers affect air flow. They can cause pressure to build up or stagnate.
The surrounding landscape also influences wind patterns. Moist air from the east often gets trapped in the valley. This can lead to fog and cloud cover. Conversely, dry air from the west can bring clear skies.
The valley location contributes to Glenside's unique microclimate. Weather systems from the east coast can get stuck in the valley. This can prolong periods of rain or heat.
