Near-normal air temperatures 

 returned to Newfoundland and southern 

 Labrador during the second half of April. 

 A steady southward advection of sea ice 

 from the Labrador coast persisted for the 

 remainder of April, maintaining the 

 southern edge near Fogo Island until 29 

 April. By month's end, the sea-ice retreat 

 was one to two weeks ahead of normal. 



In April, one iceberg passed south 

 of 48°N; the monthly average is 122. 



May 



above normal. 

 Early in the 

 month, sea ice 

 retreated from 

 northeast- 

 Newfoundland 

 waters at a 

 pace that was 

 three to four 

 weeks faster 

 than normal. 



Because 



of the 



disappearance 



of sea ice 



from the Strait 



of Belle Isle, 



the Canadian 



Coast Guard 



recommended 



use of this 



passage for 



transatlantic 



voyages on 12 



May 2005. 



With the 



exception of widely separated strips and 



patches, sea ice had cleared from the waters 



south of Hamilton Inlet by mid month. 



At the beginning of May, there was a 

 widely dispersed and sparse iceberg 

 population between 48°N and 55°N (Figure 

 21). By month's end, the population south of 

 Hamilton Inlet had dwindled to a few 

 inshore icebergs. 



One iceberg passed south of 48°N 

 during May; the average is 150.

The average air temperature in St. 

 John's was near normal during the first 

 half of May, but it was much warmer 

 than normal in both northern 

 Newfoundland and Labrador. St. 

 Anthony was nearly 4°C above normal, 

 while the daily average air temperatures 

 in Goose Bay and Nain were 2°C-3°C 



Sea ice continued its rapid retreat 

 northward along the Labrador coast in June, 

 aided by air temperatures that were above- 

 normal for the month and warmcr-than- 

 normal sea-surface temperatures (Figure 

 22). By the end of the month, ice departed 

 Labrador's coast, about three weeks earlier 

 than normal.
