Bukshs notes that folk signs indicate a snowy winter. In particular, this year there are many acorns on the oaks, and the hazel has produced a rich harvest. A good harvest of hops, according to him, also foretells precipitation at the end of autumn and a snowy start to winter. At the same time, the swamp birches are beginning to yellow from the lower branches, which is considered a sign of a prolonged autumn and a late arrival of winter.
The weather conditions in March, May, as well as on August 15 and 24, according to Bukshs’s observations, were rather dry, which may foreshadow a relatively dry September and a pleasant Indian summer. Swallows are also not in a hurry to leave, which is considered a sign of a warm start to autumn.
Overall, September is expected to be close to the climatic norm, but with a tendency towards higher temperatures. Precipitation will be unevenly distributed: in some areas, it will be more than usual, while in the east of the country, it will be less.
In the first half of September, the daytime temperature will predominantly be +15…+20 degrees. Occasionally, light rains are expected, which may intensify in some places.
By mid-month, it will become cooler: daytime temperatures are forecasted to be around +12…+17 degrees, while at night, temperatures may drop to +3…+7. In some areas, the first autumn frosts are possible.
In the second half of September, it may become warmer and drier again. Around September 21, daytime temperatures could rise to +15…+20 degrees, and in the last week of the month, to +16…+21. With clear skies, it will be colder at night, around +5 degrees, however, Bukshs does not expect serious frosts yet.
The first half of October, according to his forecast, will also be relatively warm, pleasant, and predominantly dry. A noticeable cooling is expected in the second half of the month, when night frosts will become more common.
Around October 20, a northwestern wind may bring rain clouds with hail and the first wet snow to Latvia.
