When Hobart locals want to consider the day’s weather they look to Mount Wellington. You can plan your visit to the Park using the 7-day forecast for the mountain.
On average, temperatures at the Pinnacle (1271m) are 10.5°C less than in Hobart, with a mean annual maximum temperature of 7.3°C and a mean annual minimum of 1.1°C. Visitors must be prepared for all seasons!
The average annual precipitation in Wellington Park ranges from about 750mm along the northern and southern foothills to about 1500mm on the higher peaks. Snowfalls can occur in the Park in any season but changeable weather and the proximity to the sea make persistent snow cover a rarity. Pinnacle Road, however, may be temporarily closed at any time of year due to icy conditions or snow (click here for latest status of Pinnacle Road, or call the Pinnacle Road Information Line: 6278 0200).
Winds are predominantly from the west and north–west throughout the year. Tasmania’s strongest recorded wind gusts, reaching 94kt (174km/hr), have been recorded on the mountain. Strong, dry, north–westerly winds can cause extreme fire weather conditions as experienced during the fires of 1967.
Since European settlement the area has experienced a number of extreme weather events. In 1872, after torrential rain, a landslip on the north west side of Mount Arthur created a temporary dam at the upper reaches of Humphreys Rivulet. An explosive roar was heard when the dam broke. The surge of water and debris destroyed bridges, houses, factories and crops, and killed one man. Floods in 1960 washed away the Fern Tree Bower, flooded the weir and inundated the lower parts of Hobart.
The Bureau of Meteorology collects weather observation data at the Pinnacle using an automatic weather station. Weather observing on the mountain is a long–standing tradition. The first weather observing stations in the Southern Hemisphere were established at the Springs and on the summit in 1895 by Clement Lindley Wragge, also known in unfavourable weather as ‘Inclement Wragge’. With Wragge’s revolutionary technique the observatories, at different altitudes, played a vital role in weather forecasting.
