I've acquired the yearly totals for all capital cities using these stations to get almost total coverage since then:

Brisbane:
1860-93 Regional Office
1994-99 RPA Hospital
2000- Brisbane

Perth:
1876-91 Regional Office
1992-93 Subiaco Treatment Plant
1994- Perth Metro

Darwin:
1876-40 Post Office
1941- Darwin Airport

Canberra:
1885-39 Queanbeyan Bowling Club
1940- Canberra Airport Comparison

Hobart:
1876-79 Murray Street
1882- Ellerslie Road
(1880-81 missing)

Adelaide:
1876-76 West Terrace
1977- Kent Town

Sydney:
1876- Observatory Hill

Melbourne:
1876- Regional Office

Totals to the end of November:
Darwin: 1875.4
Brisbane: 1178.8
Sydney: 1070.6
Melbourne: 683.2
Canberra: 663.8
Adelaide: 504.8
Hobart: 490.0
Perth: 486.4

If Perth remains on the bottom, as far as I can see, that will be a first. (?)

Yeah, Adelaide has only been wetter than Perth on three occasions: 1877, 1979 and 2001
Melbourne has been on 12 occasions, last was in 1993.

Rain? What is this thing called rain?

2010 = Hottest November on record for Perth with an average temp of 29.6C, 3 C above average

What about Hobart - everyone thinks Tassie is always wet - not true as can be seen. Even in "normal" years, Hobart is statistically the second driest capital City. Just a bit drier than normal this year.

Australia is so big that when someone is very wet, there is nearly always the "other side" that is then very dry.

Tassie may not get huge totals (apart from the west coast) but it rarely stays dry for long which is why I believe total raindays are a better measure. Same logic applies to the Pacific Northwest and most of Western Europe.

I feel for Perth though as it relies on strong fronts for significant rainfall(SAM must be a good boy). If these winter rains fail you can't make up the deficit, unlike in parts of the SE where the gulf trough can deliver in the warmer months.

Having lived in Hobart for 10 years I can say that my experience was that an odd light drizzly shower may pass through in the night and it is therefore considered a rain day. The actual day was usually dry. It's also though a place where it can drizzle all day long for 2mm or so. Not often does that really happen but Hobart rarely actually sees big rain drops in my experience. It was very obvious how much "heavier" the rain is back in NSW when I moved back here.

Hobart also has the second highest number of sunshine hours of the state capitals, only marginally pipped by Adelaide. I think that stat tells quite a story too.


Most visitors to Hobart region in Jan/Feb are shocked to see bare earth and brown or no grass, dry forests etc. However that is the norm for the SE of Tas.

I thought some of Hobart was extremely wet this year and the other side was very dry.

The sad reality is Perth will have to wait 4 months (April) maybe 5 months (May) maybe at the worst (depending on how 2011 goes) 6 months before we see "decent rain" again due to the seasons.Even then if the IOD or SAM is not in the correct mode we could be stuffed yet again.

Last time we had a decent May rainfall was back in 2005 frown We also got huge rainfall totals in May and June 2005 I am not sure what happened to cause that. We ended up with 875mm that year followed by 440mm the following year, 2007 was 700 and something 2008 was 804mm 2009 was back in the 600's and 2010 is just like that 440mm in 2006 again.

You could safely say that Perths climate goes by the book when it comes to the seasons. Dry summer and wet winter. Thats how its supposed to be :)I think Also perth could be on par with a similiar climate to California??? .I think the same rule applys in America,where the west is a lot drier than the east.

Indeed, especially in inland areas such as Colebrook and Oatlands. You could be forgiven for thinking you're in South Australia somewhere.

Aaaah you do know the place. Yes many bare hills in those areas, The Oatlands area and others nearby are double rainshadow areas and have very low rainfall, some places only about 400mm per year. They green up but the cover is usually VERY thin and is gone quite quickly as Summer rolls on.

The SE forest are sometimes very dry by Feb and have huge fuel loads, very dangerous when the 40 degree days come. Tassie has some quite nasty fires at times.

Hobart is struggling to make 500mm this year (although last year was big) 500mm is not much and is certainly way below what most mainlanders (sorry north islanders) would expect.

Hobart is like London. Cool temperatures in summer on average lead to lower evaporation, therefore more moisture in the soil than a place that may have a similar or higher annual rainfall but gets big prolonged heatwaves in summer that dry everything out to a crisp. Eg. places like Wagga Wagga and Cowra in NSW.

You can probably bump Canberra up a place in that ranking, considering it's only to the end of November. We obliterated our average monthly December rainfall within 36 hours of December starting (80+ mm in the last 2 days).

And on top of that, CBR Airport is actually a fairly 'unlucky' station this year in terms of rain. Tuggeranong (which is still in Canberra itself) is well over 900 mm for the year-to-date. So much of the Canberra urban area has been wetter this year than the airport obs would indicate.

This, as you can imagine, is absolutely bloody fantastic after a decade of crippling drought in SE NSW/ACT. I was beginning to think it would never end. Even as recently as last year, I finished up with only ~420 mm YTD.

It is very unusual though for Perth to be driest - particularly drier than Adelaide. It usually gets reliable winter rainfall that is sorely lacking in other areas. Apparently not this year though.

Brisbane: 1389.8
Sydney: 1120.8
Canberra: 939.2
Melbourne: 738.0
