Editing Operation Sea Lion (section)

=== Weather ===
From 19 to 26 September 1940, sea and wind conditions on and over the Channel where the invasion was to take place were good overall, and a crossing, even using converted river barges, was feasible provided the [[sea state]] remained at less than 4, which for the most part it did. Winds for the remainder of the month were rated as "moderate" and would not have prevented the German invasion fleet from successfully depositing the first wave troops ashore during the ten days needed to accomplish this.<ref name=Fleming259>Fleming, p. 259</ref> From the night of 27 September, strong northerly winds prevailed, making passage more hazardous, but calm conditions returned on 11–12 October and again on 16–20 October. After that, light easterly winds prevailed which would have assisted any invasion craft travelling from the Continent towards the invasion beaches. But by the end of October, according to British Air Ministry records, very strong south-west winds (force 8) would have prohibited any non-seagoing craft from risking a Channel crossing.<ref name=Cox187>Cox, p. 187</ref>
