Considering every wind turbine needs 9 mph or more to become effective. Here is the UK daily average for the last 23 years, wind speeds (MPH) for maximum, minimum and mean for each month
Fig 3 UK daily average wind speeds (max, min, mean) for the last 23 years
For 6 months of the year (April to September) mean wind speeds do not reach the required cut-in speed of 9 mph.
On a daily basis wind normally increases (greater temperature differential) diurnally and decreases (less temperature differential) nocturnally. Of course, it also depends on the airmass and the atmospheric pressure. All of these factors are embedded in the above table.
The UK will never be the "Saudi Arabia" of wind generated electricity
