Climate
Winter:In the south of Newfoundland, winters are mostly mild. Ice is usually light or non-existent off the south coast, allowing temperatures to be moderated by the open water. It is not uncommon to experience interludes of mild, above freezing conditions with temperatures climbing to 5 to 10 degrees Celsius with strong winds and rain. Surface wind speeds are at average 20 to 30 km/hr around the coasts with 50 to 80 km/hr sustained during low pressure systems. Very strong gusts 120 to 140 km/hr are a feature along the south and west coasts of the island whenever strong offshore winds come from the hills inland, especially at narrow valleys exit towards the sea as is the case in Grey River.
Spring:Average air temperature reaches 0 degrees Celsius by April. From April to June, stormy weaher relaxes and it is good to experience dry, fair, and mild daytime conditions aga.
Summer:By early July, summer weather has begun. The pattern of summer temperatures is determined by prevailing wind direction and distance from open salt water. The average air temperature for July is 10 to 15 degrees celsius. Southern coastal areas cool overall as dominant onshore winds are chilled by sea surface temperatures of 10 to 13 degrees celsius, making sea fog regular. However, these onshore winds also moderate nighttime temperatures, extending the frost-free season to almost five months. The annual number of frost-free days is between 130 and 150. Toward the end of August into September, there is a great possibilities for a tropical storm to hit the south of the island, resulting in strong winds and heavy rainfall.
Fall:The first occurrence of air temperature below 0 degrees celsius is normally in mid-October, resulting in a weakened form of "Indian Summer". It is characterized by a period of sunny, warm weather, after the leaves have turned following an onset of frost, but before the first snowfall, The first snowfall of a small amount is in mid to late November. Heavy rainfalls are frequent this time of year as well.
