Tropical nights are defined as a 24-hour period when the minimum temperature doesn’t fall below 20.0 °C.

Maybe we will see some tropical nights over the weekend across the southeast of England but not last night even in the centre of London. I did notice a number of stations reporting overnight minima [18-06] no lower than twenty degrees but not in good old blighty. Things are set to get even steamier over the weekend so you never know.
