long range weather

They've got 28-day and 12 month forecasts here. It's a new site design, apparently (i've never used it before).

The reasonably accurate forecasts can be found here:

http://www.bom.gov.au/climate/outlooks/#/rainfall/summary

I use this for more accuracy closer to the time I am interested in.

I have used this one since 2001 and find it is about as good as you will get.

Hope that helps.

Here is my forecast for one month out. It will be hot or cold, and sunny or overcast, and raining, or dry.

Or putting it another way aligned with the new BOM methodology. There will be a 50% chance of rain.

Prior to going away on trips in the past, I've kept a close eye on long range forecasts from the BOM, Accuweather and Elders. IMHO it's an exercise in wasting time.

Until it gets to about 5 days out, the forecasts are highly unreliable. The long rang forecasts change every day until the dates you are interested in get close.

The most reliable predictor is going by climate averages for the period you are interested in.

Meteorology? Long range forecasts? Short term forecasts? PLEASE.....
How it is considered a science is beyond me. All last week we were warned by every "forecaster" in the land, that Sydney was going to receive 4 months of rain over the next few days. 4 months worth of Sahara desert rain maybe. I think we had 4 drops in total.

Just have to go and hope for the best I'm afraid.

Elders use Weatherzone, who use some long range models to go out 28 days. They talk about rainfall probabilities NOT actual amount, so a high probability may mean they are very confident of receiving something, but they won't forecast whether it's 2mm or 20mm.
You need to pay a small subscription fee and the EO response site doesn't let me cut and paste the output.
What they are presently saying is for June no rain forecast before 19 June.
This gets updated daily and can change.
Shorter term there is the Bureau 10 day ACCESS model, again subscription needed, and it is saying no rain through to next Saturday.
WX Maps is free but hopelessly overestimates the amount of rain actually received, but at least it's good in the 7 day period of forecasting whether it will rain.
The bureau 8 day forecast is the best free one I know of, there is a free German based one which again is better than WX Maps. I hope these links work out

Bureau Of Meteorology 8 Day Rain Forecast

If you find better systems let me know, as having access to something reliable 4 weeks out, would earn you more money than knowing the winner of next week's horse races !

willy weather but like most 7 day forecast is best you can get -certainly give more info for a specific place than BOM does

available either as smart phone application or internet via lappy/computer

All of the forecasts are just an educated guess at best , so till it happens who really knows?
