I've been off-line for a week, courtesy Telstra and a mysterious "outage". Anyway no frost all week even though it has been very cold, the cloud has kept the nights warm, plus all the standing water keeps things warm,almost like living near the sea. Tonight looks cold but cloudy and then we are forecast a spell of warm weather. Everything is flowering very late due to the cool spring. the cherries and european plums have just started and the shiraz buds are swelling enough to be damaged by frost. i have got the frost sprinklers for the shiraz ready but I don't think I will need them tonight. The apples are just about to start. Of my peach trees red haven and anzac have lost most of their crop but will have a couple of dozen peaches each, fragar and peacherine still have good crops, as do some nectarine seedlings growing on my top dam.

Must be safe soon? Especially this year, frost not as prevalent. As you obviously know - a rogue frost can catch us unawares. Tricky little beasts.

Another month yet Dave till the risk of frost has passed.Most people in BX and orange don't plant tomatoes until the middle of november.
Tonight the BOM is predicting 6 but with a clear night and high pressure I think there could be a frost tonight. Maybe they think the cloud down south is headed this way. I hope they are right.

It's down to 7 already with a clear sky and no wind. No cloud on the satellite so a frost seems fairly certain. All the standing water at my place might keep the place a bit warmer, due to the high specific heat of water.
It's down to 5.6 at 9.30 at bathurst airport, the forecast minimum of 6C seems a bit off.

Well some cloud did come over, Bathurst and Orange never got below 5C, though it got down to 3 at my place. I'm not sure how the BOM forecast that small area of cloud, it seemed like a fluke to me.
next risk of frost is after the cold front, wednesday morning. I'm hopeful the BOM can arrange some cloud to keep the frost away.

The wisteria is flowering really this year,a sight we don't see very often. Most years we get one bad frost that kills all the buds. planting wisteria is very optimistic in bathurst.

Wednesday, thursday and friday morning look dangerous. Hopefully cloud will keep tuesday night warm, then there might be easterlies for thursday and friday morning. At least the forecast doesn't go below zero, so any frost should be mild. The big danger at this time of year is sub-zero temperatures that kill all the fruit. Due to the cool spring most of my apple trees haven't flowered yet which is good, cider is my main crop.

Got down to 1c this morning, a light frost. I gotup at midnight and it was 3 and a clear sky so I went out and turned on the frost sprinklers for the vines. I have to turn them on before the water freezes or the filter and sprinkler jets will clog with ice. Now I can't turn them off till the temperature rises because the heat that was released by the water freezing will be reabsorbed as the ice melts and freeze the buds.

I saw canberra got down to -1, that will be a concern for the vineyards there. Tonight is predicted 4c so hopefully I can get a good night's sleep.

Tonight the frost potential forecast says 5.8 for bathurst so hopefully the clouds will keep us warm tonight. Tomorrow an easterly wind is forecast which should keep the frost away for friday morning.

Tonight the forecast is for 1.5C and some frost. With some cloud around and winds from the east I'm hopeful it won't get that cold.

There is a decent easterly blowing tonight, the katabatic wind off the winburndale ranges. Once the easterly starts blowing there's not much chance of frost unless it gives up in the night. Usually it blows all night.

Well the easterly dropped right away, at 3am it was 4, by 6 it was down to 1. So it was a brief frost, not like the other night when it was 3 by midnight. There doesn't appear to be much damage, I think the frost was only low down and didn't get into the branches of the fruit trees. My fig still has fruit, the first time it has ever had a decent crop developing at this time of year.

There would have been a few light frosts about this morning, going by the Orange AP overnight trace. Couldn't see any sign of it on the ground though, not that one would expect to given the thick green foliage that is present.

Yep, my very young fig tree, too, has the earliest fruit of its 5 year career. The other fruit trees are quite delayed with the cooler conditions as well as very wet feet.

Dealing with frost is like that. Sometimes the difference is less than one degree, the difference between losing your crop and getting plenty of fruit. Every little bit of protection helps - the bird netting on my vines, growing trees tall and dense to get maximum blanketing, the new dam near my orchard.

Then sometimes you get -2 in the middle of october and there isn't a thing you can do.

got down to 2 last night, but no frost to speak of. A continuation of the pattern of never quite getting to zero.

It's already down to 7, clear calm night. The satellite shows cloud on the way, otherwise it might be a frosty night. Forecast is for minimum of 3, frost risk forecast says 5 so hopefully it will be alright. Down to 4.5 at orange.
