At Wanstead, the winter smoke figures showed a decrease, whilst the S.02 an increase, the summer figures as at Woodford remaining almost the same as 1961. The increase was due to a period of fog with accumulated pollution in December, similar in most respects to that of 1952.

The highest reading of the fog period on Wednesday, 5th December, was 2,392 for smoke and 2,503 for sulphur dioxide. In other words, the smoke concentration increased by almost nine times and the S.02 by eight times. At Wanstead, the average for the week prior to the fog was 223 for smoke and 266 for S.02. The highest reading here also on Wednesday, the 5th December, was 1,560 for smoke and 1,619 for S.02.
