It's unusual occurrence in my neck of the woods, but we're in a moderate drought. Rain has been sparse, and none is forecast for the next week. That will bring more stress to the trees, and anything needing to be saved will have to be watered.
The vegetable plants are requiring some water daily, since there are few clouds, the humidity is lower than normal, and the hot sun is drying everything more during the 93 degree afternoons. The grass is starting to stress, and it won't be long before a burning ban is declared.
Back in the nineties, we had a brutally hot summer. Afternoon temperatures were in the triple digits, and for one week, the temperature on our project site was around 108 degrees. We'd start at 6:00 am, if not earlier, and by 2:00 pm, everyone had enough, so we'd stop by 2:30. A few of our hands had to take a few hours in air conditioning to ward off the effects of heat exhaustion. Electrolytes were mandatory to survive, and I'd know when someone needed to take a break by their inability to get enough water. Too much only leads to vomiting and more heat exhaustion.
Earlier than usual, we were rewarded with a real cold front in early September. It broke the heat, morning were comfortably cool, and the afternoons were pleasant. We needed it, and were glad for the change.
Hopefully this summer won't be a repeat. If so, I have a huge amount of empathy for those that have to work outside.
