Daily Minimum Temperature Changes in August
Similar to the maximums, average minimum temperatures increase through time: but under the low scenario, there is a noticeable slowing after about the 2040s; and, under the high scenario, and they accelerate after about the same period. By the 2080s, the probability band for the high scenario is much wider and flatter than the low. Averages for night temperatures could reach over 20ºC under the high scenario. Spatially, you can see that temperatures increase towards the south-east of England. August 2080 temperature curves are very slightly wider than for the June-August Summer season but they are skewed more towards lower temperature changes. The change in temperature of the coldest night is likely to be approximately: approx 1.5ºC warmer under the low scenario and approx 2.5ºC under the high scenario.
Under the Low emission scenario, there is a 67% chance that average daily minimum temperatures for August:
- By the 2050s, will be between 12.2ºC and 14.6ºC. This would be between 1.2ºC and 3.6ºC warmer than they were in the 1970s.
- By the 2080s, will be between 12.3ºC and 15.4ºC. This would be between 1.3ºC and 4.3ºC warmer than they were in the 1970s.
Under the High emission scenario, there is a 67% chance that average daily minimum temperatures for August:
- By the 2050s, will be between 12.5ºC and 15.4ºC. This would be between 1.5ºC and 4.4ºC warmer than they were in the 1970s.
- By the 2080s, will be between 13.4ºC and 18.1ºC. This would be between 2.4ºC and 7.1ºC warmer than they were in the 1970s.

Estimates for the highest and lowest temperatures are only available at a seasonal level. It is therefore sensible to check how the seasonal averages compare to the monthly averages.
