The heat has been so high I have almost gone and got adhesive hooks to hang dust sheets in front of the windows. I haven't. But it's tempting.
Living room hit 30c yesterday evening, largely because it's a few days in and I can't cool it off very well overnight. Small window that is only opened a crack because we don't want the cat to get out. Suppose that is another thing I should probably do, get some kind of net I can put over the window so I can open it more at night.
