The line running through the bars is the daily average over those 10 years, so you can see the typical shape of the month at Bristol.

A narrow band means the temperature on that day has stayed close to the average year on year. A taller band means it has swung more, often because of changeable weather around that time of year. Hovering a day pulls up its low, average, and high.

Bristol Location

51.4545, -2.5879

51.45451, -2.58791 View on OpenStreetMap →

Bristol sits at 51.4545°N, 2.5879°W, on the coast of England, United Kingdom. The marker on the map shows the spot the readings on this page come from. It usually sits a short distance from the town centre, out on the open water itself, so the numbers stay tied to the coast rather than a generic point inland.

Coastlines bend, headlands focus the water, and the temperature can run noticeably differently between two beaches that look close together on a map. Comparing nearby locations is a quick way to see how local geography is shaping the readings.
