Summer (June to September): Usually provides warm and dry weather, with the odd occurrence of a heat wave. Temperatures range from 15 degrees Celsius to 35 degrees Celsius. This is the best time to visit Newcastle Upon Tyne as the variability in the weather is the least in summer.
Autumn (October to November): Warm and sunny by day and rather cool by night. Most likely a good season to visit this place.
Winter (November to March): Cold and dry, fog and mist are a common occurrence. Snow usually falls for around 14 days in the season and temperatures range from -12 degree Celsius to 7 degrees Celsius and this time is considered as off season in Newcastle.
