Hmm i think May and September. I like it when the weather is mild as I'm one of those annoying people that will whinge when it's hot but then also whinge when it's cold
Pre covid it was either June or July (lots of festivals and fun stuff going on ) I also love the run up from early November through to Christmas - Iโm not even a big Christmas person but I love the festive feeling, going to markets, getting a mulled wine mmmm
