Pear Blossom??

So, it's not only me who's confused by the varied weather recently. We've had turbulent wind, chilly nights, torrential downpours, cool grey mornings, overcast afternoons and then suddenly, a return to the heatwave with blazing hot sun for the last 2 days.
This seem to have confused one of my pear trees - which has produced these lovely little blossoms at the end of one branch. The bees are loving them at least, but I suspect any resulting fruits will be doomed long before they're ripe.
