Within 10 miles contains only modest variations in elevation feet. Within 50 miles contains significant variations in elevation 3, feet. This report illustrates the typical weather in Sydney, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Sydney.
For each station, the records are corrected for the elevation difference between that station and Sydney according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. The estimated value at Sydney is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Sydney and a given station.
To get a sense of how much these sources agree with each other, you can view a comparison of Sydney and the stations that contribute to our estimates of its temperature history and climate.
Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. All data relating to the Sun's position e.
This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a kilometer grid. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: 1 are based on computer models that may have model-based errors, 2 are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and 3 have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.

Sydney experiences an urban heat island effect, making certain parts of the city more vulnerable to extreme heat, particularly the west. Efforts have been introduced to investigate and mitigate this heat effect, including increasing shade from tree canopies, adding rooftop gardens to high rise structures and changing pavement colour.
Sydney is prone to heat waves and drought, which have become more common in recent years. Summer in Sydney tends to vary, but it is generally warm to hot.
At times, sea breezes do eventually reach the inland suburbs later in the day and would moderate the temperatures and raise humidity. The average 3pm dewpoint temperature in the summer ranges from This happens after the northwesterlies are carried entirely over the continental landmass, not picking up additional moisture from a body of water and retaining most of their heat.
On these occasions, Sydney can experience the fury of the desert climate , although they are often ended with a Southerly Buster , which is a cold front that sweeps up from the southeast abruptly cooling the temperature. At times, this cold front would bring thunderstorms , rainfall and gale winds. The highest recorded maximum temperature at Observatory Hill was The highest recorded minimum at Observatory Hill is A similar minimum temperature has also been recorded in the western suburbs.
Although, unlike late summer, the nights may be seemingly cooler and crispier. The transition from late summer to autumn is gradual, where noticeably cooler and crisper conditions taking in affect by around April. Temperatures in autumn are usually consistent and stable, lacking any extremes that tend to be experienced in spring and summer. Due to moist easterlies that prevail in this season, foggy mornings and overcast conditions should be expected. The lowest maximum temperature in autumn is Such low temperatures may provide mild to moderate frost in the western suburbs.
The lowest maximum temperature in Liverpool was 8. Similar low maximums have been recorded in the Sydney region in winter. Fog is common in winter mornings, namely in June when moist easterlies dominate. The western suburbs are more prone to fog than Sydney CBD. Heavier rain and cloudiness are also to be expected more in June, on average, than the latter winter months.
The dry westerlies also bring more sunny days, hence why August has the highest sunshine percentage than any other month. The lowest recorded minimum at Observatory Hill was 2. The lowest recorded maximum temperature at Observatory Hill was 7. Early spring is rapidly transitional. These conditions would be rare in September, but not unheard of. Extreme, changeable and inconsistent temperatures are much more prevalent in spring than other seasons.
Such extremes usually happen in mid-late spring. Other seasons seldom see such fluctuations in a day's span. Furthermore, the diurnal range is higher in this season than it is in autumn. The lowest maximum temperature in spring was 9.
