USA Atlantic Coast climate
The winter months are cold on the eastern seaboard of the USA, and the snowfall accumulation reaches its maximum in February. New York is capable of receiving some exceptional snowfalls at this time of year. Daily average maximum temperatures only reach about 4-6 °C (39-43 °F) with a poor average of 5-6 hours of sunshine. An average of 18-21 days are dry.
The onset of spring produces a gradual thaw, until by the end of May, nature has produced her most lavish floral displays. The transition from winter to summer happens quickly from mid-April onwards, and May is normally a warm sunny month. Daily average monthly temperatures range from 9 °C (48 °F) in March, to 21 °C (70 °F) in May. However, in May, temporary relapses ('Dogwood Whites') are common, and nights can still be cool. Average dry days number about 19, whilst there are approximately 7-8 hours of sunshine on average per day.
In summer, sea fog can be a problem around the coasts, and excessive heat and humidity in the cities can cause a wide range of problems to the locals. Average daily maxima can reach 28 °C (82 °F), 10 hours of sunshine is the daily average, whilst about 21 days on average are dry.
In the autumn, parts of the area are blessed with a magnificent display of colours as the trees change in readiness for the winter. Average daily maximum temperatures fall rapidly during this period, ranging from 24 °C (75 °F) in September, to 12 °C (54 °F) in November. The average number of dry days is about 21, whilst there are 6-8 hours of sunshine on average each day.
