Arashiyama's peak kouyou forecast is now expected around 29 November, said the Japan Meteorological Agency (JMA), a delay of roughly one to two weeks from the usual period. The agency forecast that the best time to view the autumn colouration of momiji (maple) leaves in central Kyoto this year will be 16 December, compared to 5 December in a typical year. The delayed changing of leaves is attributable to unusually high temperatures well into October in recent years, the JMA said, citing this year's excessively hot summer and prolonged late-summer heat.
