Seasonal variations in wind are not as marked over Victoria as they are over the extreme north of the continent. It is also often coupled with flooding in tributary streams. Usually, such days are the culmination of a period during which temperatures gradually rise. The frequency of these systems and the amount of rain associated with them varies from season to season. The most reliable rainfall occurs in the Western District, where the passage of cold fronts, especially in winter, bring frequent light to moderate falls. When temperatures are high, and there are N to NW winds from the dry interior, humidity is low. All Year Climate & Weather Averages in Melbourne. Based on weather reports collected during 1985–2015. The mid-morning (9am) relative humidity is usually close to the daily average relative humidity, because the temperature at that time is close to the average temperature. In fact, the rainfall in any particular season may be close to average, but if it all fell in one event at the wrong time in relation to the growing cycle of a particular crop, then that rain would be of little use. October is also the wettest month with Melbourne's average annual rainfall coming in at approximately 600mm. As a consequence of the weaker jet streams, vertical motions in the atmosphere are also weaker. Mean Temp: 61 °F. Brisbane. After several years of increasing tension among the sepoys (Indian soldiers) of the British East India Company's Bengal Army, the sepoys at Meerut, 60 miles (97 km) north east of Delhi, openly rebelled against their British officers. Weather patterns are shifting as the western Indian Ocean is warming faster than the east, increasing the likelihood of more frequent and intense dry spells for south-eastern Australia. Display Your Local Weather. Victoria gets most of its rain in late fall and winter, while the late spring and summer is very dry. The intensity of dust storms has been reduced in recent years with improved methods of cultivation, soil conservation and pasture improvement, which particularly included the growing of lucernes on lighter soils. Communities can be isolated for long periods. Usually, they are associated with anticyclones over Tasmania and fine weather over most of the State. Dew Point: 47 °F. Wilsons Promontory, an exposed locality along the South Gippsland coast, illustrates some of these features. February is the hottest month of the year, with January only slightly cooler. (2012, August 8). Conditions in these latter areas would be almost unbearable at times were it not for the relief afforded almost every day by this breeze. The first written record of a fire causing major damage in Victoria was on 6 February 1851 (Black Thursday). Another bad form of dust storm though less frequent, is associated with persistent northerly winds in which local dust and wind borne dust from districts further north combine. It often springs up during the night, often suddenly, and continues after sunrise until the land surfaces are sufficiently heated again. The chance of measurable rain on BC Day is nearly twice as high in Vancouver (16.7%), and nearly four times as high … Therefore, local dust may be fairly frequent, provided dry particles are available. A warm coat and umbrella are sufficient weather protection in these mild coastal climes. CTV News Vancouver Island and Victoria weather forecasts and current conditions for Vancouver Island and surrounding area. From April to October the weather is hot. Saturday Fog then sunny, warm in the southwest. Even there, however, occasional severe droughts occur. Snow has been recorded in all months over the higher Alps, but main falls occur during the winter months. Report These are the real-time observations from the weather station at Victoria Airport. The valley breeze is well developed in many hilly area of Victoria, being the result of differential cooling after sunset. Under certain conditions, severe thunderstorms develop and produce damaging phenomena such as tornadoes, destructive wind gusts, large hailstones and flash flooding. The annual mean … Thus, dust storms have their maximum frequency in the summer months when surface heating is strongest and the soil normally driest. Just wondering that with last weekends conditions, this weekends forecast and next weekends forecast (long range but still) that weather patterns in victoria are some sort of cycle? Easterly winds are least frequent over Victoria. The exception is an area covering much of the far southwest of the State, excluding the exposed coast. In Australia, where surface water storage is vital over large areas, evaporation is a highly significant element. Severe thunderstorms are most likely to occur during the late spring and early summer months with the majority developing during the afternoon and evening. Values are below 10°C over elevated areas, but otherwise they are mostly between the low-teens and the mid-teens. Friday, 18 Sep 2015 at 1:36pm. Humidity: 63%. Occurrences are, generally speaking, more frequent, and tend to be more serious, in southern, eastern, and northeastern rivers. Climate of Victoria Introduction. The variety of climatic conditions and vegetation across Victoria results in varying degrees of threat from bushfires. The average pattern is complicated by the vagaries of the season. Mountain and coastal river flooding generally occurs more quickly than inland river flooding. Fog then sunny, warm in the southeast. These frequencies could recur with extreme climatic conditions, such as occurred in the ninety months from 1895 to 1902 when Victoria experienced its most intensive recorded drought. The rainfall over East Gippsland is less reliable, with lengthy dry periods broken by relatively heavy rainfall events caused by low pressure systems off the NSW south coast or in eastern Bass Strait. As well as being interesting from day to day, weather records are of vital national importance. Most dust storms are associated with winds from between northwest and southwest and on most occasions a sustained wind speed of approximately 25km/hour is sufficient to raise a dust storm from dry soil. Warrnambool, along the State's west coast, is one city markedly affected by the sea breeze phenomenon. High Temp: 73 °F. On rare occasions, extreme heat may continue for as long as a week with little alleviation. Snow in Victoria is confined usually to the Great Dividing Range, which at intervals during the winter may be covered to a considerable extent, especially over the elevated eastern section. The remaining southern districts often obtain a measure of relief from showers produced by passing cold fronts. Dust storms occur mainly during the daylight hours but the phenomenon has occasionally been observed at night. Apart from the heavier falls, which are an intrinsic characteristic of the climate of these areas, frequency may be increased in many instances by valley contours, and damage is often greater because of the higher density of adjacent property and crops. Victoria is home to three separate climate zones including alpine which is cold, southern coastal which tends to be cooler and northern/western which is generally a little warmer. Fires become particularly dangerous when the strong northerly winds are followed by a wind shift to southwesterlies bringing a cool change. The ridge was of hard rock, about 60 feet (18 m) high, and ran from a point only 1,200 yards (1,100 m) east of the Kabul Gate on the city walls to the Yamuna River 3 miles (4.8 km) north of the city. Instruments near expanses of water such as coastal inlets, rivers, reservoirs or irrigation systems may record lower evaporation than the surrounding country due to local effects on meteorological elements, notably humidity. There are the warm and dry grasslands of the State's northwest, covering the Mallee, and much of the Wimmera and Northern Country. All districts of the State have experienced some flooding. It is difficult, however, to compare the severity of different bushfires, since the tragic consequences cannot be quantified. The average number of days on which thunderstorms occur in Victoria each year varies from about 10 along parts of the coast to in excess of 30 about the highlands. The Victorian snow season can also not be compared with the long and cold winters, for example, of eastern Europe, northern Asia, or the northern interior of North America, where a snow cover forms early in winter and persists throughout the season. Low Temp: 44 °F. As a result, the trade winds reverse and below towards the warm water and deny the Australiasian / Indonesian region its moisture. Local dust may be lifted by winds from any direction on reaching a force of about 20km/hour. The first of these is the "El Niño - La Niña" phenomenon. Over the elevated areas that form the Central Divide and the Northeast Highlands, maximum temperatures decrease steadily with height, being as low as in the mid-teens in the very highest localities. How To Pick A Camp Spot Based On Victoria’s Freak Weather Patterns. The State of Victoria experiences a wide range of climatic conditions. Day temperatures on the coast average in the low-teens in July; much the same value is recorded over the wheat belt, and temperatures are only one or two degrees higher in the far northwest under conditions of few clouds and relatively profuse winter sunshine. Hourly. However, such relief does not always arrive so soon, and periods of two or three days, or even longer, have been experienced when the maximum temperature exceeds 40°C. In such circumstances, water vapour in the atmosphere will begin to condense and dew, mist and fog will begin to form. Evaporation from a free water surface depends on a number of climatic elements, mainly temperature, humidity, and wind. Another example of the diurnal variation is the valley or katabatic breeze, which brings cold air down valleys during the night. On summer mornings, 29% of winds are offshore (from the NW, N, or NE). Sometimes, the early morning temperature falls so far that it reaches the temperature at which the atmosphere is holding as much water vapour as it possibly can. The brief, mild winter starts in late November, peaks in January and heavy fog often occurs. The "Indian Ocean Dipole" operates over the ocean areas to the northwest and west of Australia. The north experiences longer, more extreme winters for which you will need heavy duty winter gear. Because of the great length of the river and shallow gradients, flood peaks move slowly and can usually be predicted with a high level of accuracy, allowing effective local action to reduce damage and losses. In Victoria, the summers are cool, dry, and partly cloudy and the winters are very cold, wet, and mostly cloudy. The Great Dividing Range, the main land feature of Victoria, also produces a cooler climate in the mountains at the centre of the state. © 2021, TravelOnline Australia Pty Ltd.ABN: 70 100 929 799.
