The moon will be full, and at its nearest to Earth for 2022, on Wednesday, July 13.
Twice or sometimes three times every year, we have these near-in moons, nowadays called supermoons. A supermoon is defined as being near its perigee, or closest point in orbit to Earth, at a time when the moon is also new or full.
The moon is the main cause of Earth’s tides. But the sun, vastly larger and vastly more distant, adds a pull about half as strong. This is why the highest amplitude of tides comes at these two near-in moons – the year’s closest new moon and the year’s closest full moon – which, in 2022, fall slightly less than half a year apart.
Where I live in the UK, there is also a heat wave rising. But its amplitude may have more human than lunar contribution.
