Glasgow has an oceanic climate characterised by cold, wet winters and cloudy, cool summers. The city has the dubious honour of being one of the rainiest cities in the UK.
December is the coldest month of the year, with an average temperature of 39°F (4°C). July, the warmest month, has an average high of 67°F (19°C).
The weather in Glasgow is known for being unpredictable. When Glaswegians joke that it could be sunny in the backyard while raining out front, it isn't far from the truth. Even if it doesn't look like rain is on the way, it's always best to keep an umbrella handy, just in case the weather turns.
