Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.

Melbourne has a temperate oceanic climate (Köppen climate classification Cfb) and is well known for its changeable weather conditions. This is mainly due to Melbourne's location situated on the boundary of the very hot inland areas and the cool southern ocean. This temperature differential is most pronounced in the spring and summer months and can cause very strong cold fronts to form. These cold fronts can be responsible for all sorts of severe weather from gales to severe thunderstorms and hail, large temperature drops, and heavy rain.

Melbourne has an integrated public transport system based around extensive train, tram, bus and taxi systems. Flinders Street Station was the world's busiest passenger station in 1927 and Melbourne's tram network overtook Sydney's to become the world's largest in the 1940s, at which time 25% of travellers used public transport but by 2003 it had declined to just 7.6%. The public transport system was privatised in 1999, symbolising the peak of the decline. Despite privatisation and successive governments persisting with auto-centric urban development into the 21st century, there have since been large increases in public transport patronage, with the mode share for commuters increasing to 14.8% and 8.4% of all trips. A target of 20% public transport mode share for Melbourne by 2020 was set by the state government in 2006. Since 2006 public transport patronage has grown by over 20%.

Melbourne has the largest tram network in the world which had its origins in the city's 1880s land boom. In 2013–2014, 176.9 million passenger trips were made by tram. Melbourne's is Australia's only tram network to comprise more than a single line and consists of 250 km (155.3 mi) of track, 487 trams, 25 routes, and 1,763 tram stops.

Melbourne's trams are recognised as iconic cultural assets and a tourist attraction. Heritage trams operate on the free City Circle route, intended for visitors to Melbourne, and heritage restaurant trams travel through the city and surrounding areas during the evening.

Melbourne is also prone to isolated convective showers forming when a cold pool crosses the state, especially if there is considerable daytime heating. These showers are often heavy and can contain hail and squalls and significant drops in temperature, but they pass through very quickly at times with a rapid clearing trend to sunny and relatively calm weather and the temperature rising back to what it was before the shower. This often occurs in the space of minutes and can be repeated many times in a day, giving Melbourne a reputation for having "four seasons in one day", a phrase that is part of local popular culture and familiar to many visitors to the city. The lowest temperature on record is −2.8 °C (27.0 °F), on 21 July 1869. The highest temperature recorded in Melbourne city was 46.4 °C (115.5 °F), on 7 February 2009. While snow is occasionally seen at higher elevations in the outskirts of the city, it has not been recorded in the Central Business District since 1986.

Melbourne is experiencing high population growth, generating high demand for housing. This housing boom has increased house prices and rents, as well as the availability of all types of housing. Subdivision regularly occurs in the outer areas of Melbourne, with numerous developers offering house and land packages. However, after 10 years[when?] of planning policies to encourage medium-density and high-density development in existing areas with greater access to public transport and other services, Melbourne's middle and outer-ring suburbs have seen significant brownfields redevelopment.

Melbourne is often referred to as Australia's garden city, and the state of Victoria was once known as the garden state. There is an abundance of parks and gardens in Melbourne, many close to the CBD with a variety of common and rare plant species amid landscaped vistas, pedestrian pathways and tree-lined avenues. Melbourne's parks are often considered the best public parks in all of Australia's major cities. There are also many parks in the surrounding suburbs of Melbourne, such as in the municipalities of Stonnington, Boroondara and Port Phillip, south east of the central business district. The extensive area covered by urban Melbourne is formally divided into hundreds of suburbs (for addressing and postal purposes), and administered as local government areas 31 of which are located within the metropolitan area.

Melbourne is typical of Australian capital cities in that after the turn of the 20th century, it expanded with the underlying notion of a 'quarter acre home and garden' for every family, often referred to locally as the Australian Dream. This, coupled with the popularity of the private automobile after 1945, led to the auto-centric urban structure now present today in the middle and outer suburbs. Much of metropolitan Melbourne is accordingly characterised by low density sprawl, whilst its inner city areas feature predominantly medium-density, transit-oriented urban forms. The city centre, Docklands, St. Kilda Road and Southbank areas feature high-density forms.

Melbourne's CBD, compared with other Australian cities, has comparatively unrestricted height limits and as a result of waves of post-war development contains five of the six tallest buildings in Australia, the tallest of which is the Eureka Tower, situated in Southbank.
