Just for fun, although attempting to do this highlighted my lack of advanced computer skills and took twice as long as it was meant to. It still could be better, but you'll get some idea.
Bristol manages a minor heatwave around the 23rd, but otherwise ranges between low 50s and high 60s. Still pretty cool at night.
Now we're into June we're basically in the 90s and staying there. Haven't really hit triple figures yet - that joy is still to come. Whether or not you Bristolians are jealous is entirely up to you. Personally, as you will have gathered, I prefer my climates temperate, but I promise not to whine about the heat for at least, say, two more blog posts (or until it hits 100F, whichever comes first).
