To provide a useful data point[1] about "non-optimal weather conditions":
> Between the 26th of February and the 8th of March the capacity factor of the national wind fleet did not go above 20%. Its average over these 11 days was just 11%, less than a quarter of their average in the month either side.
So it is possible for wind power to fluctuate by a factor of 4 on a national-weekly scale. Offshore conditions are less variable than the UK average, but even over-provisioning the amount of wind power by a factor of 3 would make wind energy more expensive than the Hinkley Point C agreed strike price of £92.50/MWh to £89.50/MWh.
