Average Temperatures – Aberdeen City

Annual Trends:
Fig. 1 demonstrates the change in maximum and minimum temperatures of Aberdeen City through the year, comparing values from 1961-1990 to those of 1991-2020. In both groups (max and min) the 1991-2020 period experienced an increased temperature from the pervious 1961-1990 period, suggesting an overall warming trend in the city.
In support of this warming trend, fig. 2 shows the continuous temperature data for Aberdeen over 50 years. The trendline displays a clear upwards trend, with a lot of variation between. Overall, temperatures in the city have been increasing over the last half century. In 2023, the annual average sat at 9.1oC, more than 1oC higher than the 1973 value of 7.9oC. 

Summer Trends:
Fig. 3 shows Aberdeen's annual summer temperatures over the last 50 years. Summer temperatures have not undergone as much of a change as the overall yearly average. These is a lot of variation in the pattern, with years of extremes such as 1996 and 1997. As of 2023, the average summer temperature sat at 14.4oC.

Winter Trends:
Fig. 4 shows Aberdeen's annual winter temperatures over the last 50 years. These temperatures are much less variable than the summer temperatures and show a more consistently increasing trend. In the last 50 years, Aberdeen’s average winter temperature has increased by more than 1oC - from 7.9oC in 1973, to 9.39oC in 2023. 

Scotland Wide Trends: 
In figure 5, Scotland’s overall average temperatures are compared to that of Aberdeen. While the Scotland-wide data set is on a shorter timescale, this comparison still offers some valuable insight:  It seems Aberdeen is of above average temperature for Scotland and is increasing in temperature faster than is typical for the country.
