Arapiles & Grampians - Weather (Travellers Guide)
7:16:01 PM

After hearing some bad luck stories, i thought it might be a good topic to write about my experiences with weather in the gramps / araps. It seems that lots of international climbers are coming to the gramps and leaving bitter about the bad weather. Anyhow these are my thoughts of 14 years of climbing there.

January & February - Often too hot for maximum sending. You will be sweating and slipping on the frictiony grips. Climbing is possible in shade. Best chances of good weather are first two weeks Jan. Early starts and late evening are good. Avoid routes requiring friction (taipan & spurt wall). Camping is tough with lots of flies. Expect average temps of 30 degrees plus.

March - First two weeks are often much like Jan Feb ( Hot ). 2nd two weeks the temperature generally plummets to low 20's. My favourite time to start climbing.

April - The best time to be there. Stable weather in the low 20's. One or two rainy days here and there.

May - The temperature can drop (Low teens) , but so can the rain. Expect whiteout / misty conditions at times. The worst conditions in the gramps are often when the mist is hanging in the air. This generally lasts a few days. Unfortunately this is rarely shown on the forecast.

June - I have only ever had dry winters in the middle of the drought. We are currently NOT in a drought. Expect rain, grey skies and the dreaded hanging mist. Avoid water streaks, or seepy crags. Its often hard to predict the good days, as the forecasts are often incorrect. Sometimes the rain lasts weeks. Its technically not cold, but the constant grey skies can be very depressing.

July - Much the same as June, with perhaps one more sunnier day.

August - I generally go to Nowra.... However, this is when the weather suddenly changed this year. Was a great month for sunny crags.

September - Yes the sun starts to come out and the crags are dry. Some showery days but generally not bad. Best conditions are generally last two weeks.

October - Apparently Chris Sharma is counting down how many October's he has to climb at his peak. This is because October is generally a stellar month everywhere. The gramps is no different. Probably the second best month to climb here.

November - A good month to climb as its dry and warm. Think high 20's to low 30's at worst.

December - Can be a mixed bag. Lately we have had very mild Decembers with temperatures struggling to get above 30. Often there will be one week with consecutive days in the mid 30's.

I hope some travellers find this useful. I hope others can add useful comments.

Spot on KP. I've lost count of the times I have heard people booking international/interstate trips to Gramps in winter then complaining.

International travellers should note that the Grampians sits on the 37th parallel of latitude (south).
Have a look at what lies around about the 37th parallel in the northern hemisphere and decide whether you'd fly there for a climbing trip in winter : Algiers, San Francisco, Athens, Seoul(!), Springfield (perhaps not on your road-trip list). The Grampians is generally low-lying but is only 100 km north-west of the southern ocean so it gets weather blasting straight in from that.

But the earth rotates about a tilted axis with north being further away from the sun than the south. How many degrees difference does that make it? I don't know, maybe somebody out there in Chockyland can let us know.

Let's not start confusing people by taking into account tilt of the earth and perihelion/aphelion effects on weather. I think the net result of those is that southern winters are on the whole marginally more cold than northern winters but who wants to do doctoral research to work out where to go on your next road trip?

1.0745 degrees, but this is only an average, as it depends on where within which millennia we are talking about, for the earth's orbit.

In a strange coincidence this figure also corresponds almost exactly to the vibration wavelength frequency of a figure 8 rap device, as used by inexperienced boulderers on the incorrect end for belaying, when they fulfil their duties to the sport climber providing transport options that they have utilised.

We need to wait for mikl to reply with the exact figures after he pulls one apart next millennia to compare to the results he has obtained over the last two millennia.

From my years of Europe I think central-north euros like to climb with around mid 10's (depending on the grades) on dry weather, which doesn't happen very often anywhere in this planet.
Anyway, a lot of people would find a way to complain even at this "perfect" conditions, so I wouldn't bother too much ;)
South Europe it's about the same as here really, well, less flies!

Thanks for the good summary anyway!

It's also worth mentioning that some out-of-the-way Grampians crags have angry falcons nesting in spring. Hence the really best time to visit is mid March to late April.

Darwin's 'Voyage of the Beagle' has some examples of N and S hemisphere snowline comparisons:- S American snowlines are (were) lower at same latitude

Yes we had a very wet spring this year. September/ October & November were not good for climbing at all!!

No sh*t!

Can anyone report the current state of Taipan seepage lines? Nether in particular, or others. Ta!
2:29:00 PM
Haven't looked at Taipan but it's been a very wet August so far. The local paper reported this morning that Grampians water catchments flowing more than usual at this time of the year.
So, my guess is that seepage lines will be seeping.
