Default Low Relative Humidity

At the time of writing,25.1525z, the relative humidity here in the lee of the Scottish Highlands is only 36%. Isn't that the sort of RH you get in some deserts during the day?

Updating my earlier post. Lowest value here was 27% just after Midday.
Lower values in Cornwall, I see.

Back in May 1964 (probably, or possibly '63) I recorded 10% RH at RAE
Thurleigh (Bedford, 03558) with temp of 25C and dewpoint of -9C.

That is a very high figure for a hot desert during the day. With a temperature of 45°C it would imply a dew-point of about 27°C and be all but intolerably sweaty. A more likely RH would be a little less than half that.
