Weather
Portland sits between two mountain ranges, the Coast to the west bringing rain from the ocean and the Cascade to the east, which stops weather from inland reaching the city. Rain falls heaviest between November and March, snow falls seldom and winter temperatures, with lows averaging less than 10°C (50°F), are generally mild. June to September are the warmest months in Portland, averaging above 20°C (68°F).
