As I write this at 10:15 PM it is still 26.6*C outside and 30.4*C inside the house. We went down this evening to water in the hope that the temperature might have dropped - but it hadn't; at least not significantly.
Spent two hours continually filling and emptying the water butts.
Everything needed a drink, though the tomatoes and grape are loving this weather. Still, as long as we keep everything watered it's looking increasingly like a bountiful year.
Salsify is looking increasingly good - no idea what it tastes like though.
