Here's how today compares...

Today's maximum temperature so far is 18.7 °C, and the minimum overnight was 14.4 °C. The average of the two is 16.6 °C, which is warmer than 71% of daily average temperatures at LMSS for this time of year over the period 1912 - 2024. The really hot and cold days (top and bottom 5%, respectively) are outside the dotted lines.

This is the distribution of temperatures typical for this time of year, which we've defined as a seven day window either side of today. Just like a bell curve, the plot is higher at more common temperatures and lower at rare temperatures.

...and the rest of the year

We've compared every day this year at LMSS to similar times of year in the past. Red days were hot compared to records; blue days were cold.
