How would you describe the weather climate in sydney?

Question by Tom: How would you describe the weather climate in sydney?
I live in sydney australia and ive never understood the weather pattern here, its either always raining non stop for a couple of weeks (last summer) and it would be dry with no rain for quite a while, some nights can be substantly warmer than other nights, the nightime temperatures are always warmer than the surroundings like newcastle, gosford etc,
Any explanation as to why?

First of all, the weather is like that through most of the NSW coast. I also live in Newcastle and the weather (i.e, raining for days, then dry for days, etc) is here too.

It’s also more chilly at Gosford and Newcastle because we’re a smaller city that’s much closer to the shore. When you live 5 mins from the beach, it’s bound to be much chillier.

    Tom this isn’t just the case in Sydney, but here in Montreal, we will have temperatures of 30 and 31, with the humidity factor, 40 plus, for a few days, then we get a low pressure coming up from the States, bring severe storms, and temperature drops 10 degrees below normal.

    This is a world wide trend not just you guys, so there is definitely nothing wrong with your weather.

    Sydney is subtropical and its climate is dictated by the movement of the sub-tropical ridge (STR). This is the band of high pressure around the globe that moves north and south with the apparent movement of the Sun. The centre of the STR is around 30°S in winter and 40°S in summer. That is Coffs Harbour to Hobart.

    When the ridge is north of Sydney, the wind is westerly and coming off the land. This produces dry weather which we usually see in August and September. The driest fortnight is the last fortnight in September – which is when Sydney held the Olympic Games. As the ridge moves south, the winds become easterly – the southeast trade winds – and, because they are coming off the Tasman Sea, they are moist. The winds are forced to rise by the mountains inland from Sydney, cloud develops and rain falls. As the southeast trade winds are strongest in summer and autumn, that is when Sydney gets the heaviest rain.

    Those same easterly winds going into Perth are off the land so Perth gets hot dry summers while Sydney gets warm wet summers. The westerly winds in winter bring rain to Perth but dry weather to Sydney. If you look at any of the State capital cities with reference to the STR you can see why Melbourne, Adelaide and Perth have hot dry summers while Sydney and Brisbane are warm and wet.

    Temperatures on the coast are modified by the proximity of the ocean. You don’t get frosts in Sydney city but you do get frosts inland west of Parramatta. Sydney’s minimum temperatures are also modified by the urban heat island effect. All that concrete and glass holding heat, together with all the cars and trucks driving around and all the lights on raises the minimum temperature of the city by up to 2°C compared with areas outside the city like Gosford.
