Summer 2014/2015 starts

Saturday 18 October             Max 26    Partly cloudy.
Sunday 19 October     Min 17    Max 29    Afternoon cool change.
Monday 20 October     Min 12    Max 23    Mostly sunny.
Tuesday 21 October    Min 10    Max 28    Sunny.
Wednesday 22 October  Min 16    Max 31    Possible shower.
Thursday 23 October   Min 15    Max 20    Possible shower.
Friday 24 October     Min 13    Max 22    Cloudy.

Winter 2014 ends

I’ve tried to use the same technique to determine winter the same way I do summer; I decided back in June that winter started. And in August, it’s over.

Tuesday   19 August Max 15 Possible light shower.
Wednesday 20 August Min 7 Max 15 Cloudy.
Thursday  21 August Min 5 Max 18 Mostly sunny.
Friday    22 August Min 6 Max 19 Mostly sunny.
Saturday  23 August Min 7 Max 19 Mostly sunny.
Sunday    24 August Min 8 Max 18 Mostly sunny.
Monday    25 August Min 6 Max 18 Mostly sunny.

A couple of days later the forecast was extended out to

Tuesday   26 August  Min 8 Max 19 Partly cloudy.
Wednesday 27 August  Min 9 Max 21 Mostly sunny.

Winter 2014 starts

So I’m trying to declare Winter. I’m going to try something like Summer, but with a 16 degree ceiling, which we just hit here in Melbourne.

Monday    16 June             Max 16    Rain at times, easing.
Tuesday   17 June    Min 10   Max 16    Partly cloudy.
Wednesday 18 June    Min 8    Max 16    Mostly cloudy.
Thursday  19 June    Min 8    Max 16    Partly cloudy.
Friday    20 June    Min 10   Max 15    Shower or two developing.
Saturday  21 June    Min 9    Max 15    Morning shower or two.
Sunday    22 June    Min 9    Max 16    Partly cloudy.

I also offer the observation that you know it’s Winter when it doesn’t feel cold anymore.

Note: The 15 degree ceiling was hit on Friday 4 July 2014, 14 degree on Wednesday 9 July..

Summer 2014 ends

Four days before the start of Winter, I’ve declared the end (our second) Summer:

Wednesday 28 May              Max 18    Shower or two.
Thursday  29 May    Min 10    Max 19    Partly cloudy.
Friday    30 May    Min 10    Max 19    Partly cloudy.
Saturday  31 May    Min 10    Max 19    A little rain developing.
Sunday     1 June   Min 10    Max 17    A few showers.
Monday     2 June   Min 12    Max 17    Shower or two.
Tuesday    3 June   Min 10    Max 18    Morning shower or two.

Summer 2014 starts

Given recent events pointed out by DavidC, I declare Summer 2014 has started. Our traditional, mid-year Summer.

Wednesday 14 May    Min 10    Max 21    Mostly sunny.
Thursday  15 May    Min 13    Max 22    Partly cloudy.
Friday    16 May    Min 14    Max 22    Mostly sunny.
Saturday  17 May    Min 13    Max 22    Mostly sunny.
Sunday    18 May    Min 12    Max 21    Partly cloudy.
Monday    19 May    Min 12    Max 21    Sunny.
Tuesday   20 May    Min 14    Max 21    Partly cloudy.

Good thing you guys voted in that Abbott government.

The upside of climate change is that I get to paint the house this week. Two weeks before the start of Winter.

Summer 2013/2014 ends

The seven-day forecast for Melbourne makes today the last day of Summer:

Wednesday                    Max 16    Showers mainly this morning.
Thursday  1 May    Min 7     Max 18    Partly cloudy.
Friday    2 May    Min 11    Max 15    Rain at times.
Saturday  3 May    Min 8     Max 14    Shower or two.
Sunday    4 May    Min 10    Max 15    Shower or two.
Monday    5 May    Min 11    Max 16    Shower or two.
Tuesday   6 May    Min 10    Max 15    Mostly dry.

Of course, Summer persists while any temperature in a week is 20 degrees or above.

Summer 2013/2014 starts

The current 7-day forecast for Melbourne:

Friday   30 August           Max 20 Shower or two.
Saturday 31 August    Min 12 Max 23 Sunny.
Sunday    1 September Min 15 Max 25 Partly cloudy.
Monday    2 September Min 12 Max 23 Partly cloudy.
Tuesday   3 September Min 11 Max 25 Partly cloudy.
Wednesday 4 September Min 16 Max 26 Shower or two developing.
Thursday  5 September Min 16 Max 20 Shower or two.

I declare summer whenever there’s going to be 7 consecutive days in a row above 19 degrees.  Previously, the earliest Summer has started was mid-September, but typically it’s been moving forward from October or November.

Remember we’ve got an election coming up in a week’s time, and that’s your opportunity to repeal the carbon tax.  Which we need to do, to keep lovely balmy weather happening in winter-time and to keep the cost-of-living down.  Remember: carbon-dioxide is food for plants, and as such good for the environment, which is made out of plants. That’s just science.

Summer 2011/2012 starts

I declare summer whenever there’s going to be 7 consecutive days in a row above 19 degrees.  And as such:

Friday            Max 22  Shower or two.    
17/09/11  Min 10  Max 25  Shower or two developing.    
18/09/11  Min 12  Max 21  Sunny.    
19/09/11  Min 11  Max 27  Showers developing. Windy.
20/09/11  Min 12  Max 20  Shower or two.     
21/09/11  Min 13  Max 22  Morning shower or two.    
22/09/11  Min 12  Max 24  Mostly sunny.

Summer.

In September.

It’s a good thing that global warming is a beat up by the greens, a front for communist interests trying to take control of our lives and introduce excessive and unneeded regulation – or else I might be worried.

Summer 2009/2010 starts

I have a algorithm for detecting summer. Seven consecutive days in a row with a temperature of or above 20 degrees Celsius. I give you Summer, from the Bureau’s seven day forecast for Melbourne:
Forecast for Monday Max 20
Forecast for Tuesday Min 8 Max 24
Forecast for Wednesday Min 10 Max 25
Forecast for Thursday Min 12 Max 28
Forecast for Friday Min 16 Max 29
Forecast for Saturday Min 18 Max 28
Forecast for Sunday Min 16 Max 26
I should also point out that I consider there to be two seasons in Melbourne: Nice-but-hot (summer-ish) and a-bit-iffy (winter-ish).

Summer 2008/2009 starts

I have a algorithm for detecting summer. Seven consecutive days in a row with a temperature of or above 20 degrees Celsius. I give you Summer, from the Bureau's seven day forecast for Melbourne:

Thursday      Fine.                                  Min  6    Max 21
Friday        Mainly fine.                           Min 12    Max 25
Saturday      Fine.                                  Min 12    Max 30
Sunday        Shower or two.                         Min 15    Max 22
Monday        Fine.                                  Min 10    Max 23
Tuesday       Fine.                                  Min 12    Max 28

I swear, this gets earlier and earlier each year.
