Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Hobart sits on the estuary of the River Derwent and opens onto cool southern seas, so water temperatures are noticeably lower than much of mainland Australia. Seasonal ranges are modest: in summer the nearshore water typically reaches about 15–18 °C, while autumn and spring generally see temperatures around 11–15 °C as the sea cools or warms gradually. Winter brings the coldest conditions, with surface temperatures commonly falling to roughly 9–11 °C. These values can vary with wind, tides and inflows from the Derwent, and sheltered bays often feel a degree or two warmer than exposed open-coast locations. Overall, Hobart’s waters remain on the cool side year-round due to its southerly latitude and oceanic influences.
