My Omega thermocouple thingie, hanging out my office window, reports
58F at 1:45 PM. A cheap Extech IR thermometer shows 61F on the
adjacent rooftop, not a bad correlation for this sort of thing. San
Francisco, about 2 miles from the beach.

Back to work.

Thats is 14.444444444 Celcius according to
Click to expand...
http://www.nomoreodor.com/fahrenheit_to_celsius_conversion.htm

San Francisco is same height as Amsterdam?
My PC says:
requested day temperature 19.00 requested night temperature 2.00
inside temperature 19.07 outside temperature 11.01
minimum inside temp 6.98 maximum inside temp 25.12
minimum outside temp -3.10 maximum outside temp 37.22
At 23:45 (evening).
The minimum was over this last winter, not much of a winter really.
It also shows the heating costs, if the power is flowing, and has a nice GUI
you can click.
The outside sensor is about 1 meter away from the ground and 20 cm from a non
heated wall.
The maximum comes from direct sunlight on the sensor.

I had a light sensor too, but does not seem to be plugged in now :)

He! We hit 64' here today at the 'hottest' part of the afternoon.
Expected to reach the low seventies by the weekend, though! :-D

Hey it's been summer here since February just across the Bay in
Dublin, CA. And it was 80 degrees in Sam Clam's Disco at the end of
March for the ESC, so stop complaining. Now I'm heading to the east
coast to show off my tan.

Yeah: on a good summer day, Sf is 60, Berkeley is 80, Walnut Creek is
100: roughly a gradient of one degree per mile.

In Los Angeles it gets hotter as you move towards the San Fernando Valley
(which is towards San Frnasisco. The maximum must, therefore, be
halfway betwee the two in Santa Barbara. No wait, that can't be right.
Bakersfield?

As you can see from the minima it does not get below 6 when it is outside -4 or so.
This because of all the electronics, the computers heat up the place, some other stuff.
Good isolation.
I usually do not activate the nighttime control, because often I work half a night or
so (until 4 in the morning..) only when I am away in winter, to prevent things from
freezing.
That once happened and is quite nasy one the temp goes up again and the water
pipes get lose...

This 10 C delta T between inside and outside shows you the thermal conductance of the
house.
Convenient to know that.
Since there is no airco, now you can see it was 40 inside when it was 30 outside last
summer...
However when there is a lot of wind, the delta t lowers a lot...
And wind is always here...

This is what I use to get a clue about wind, sat images of clouds, pressure,
and temp all at the same time for west Europe.

I know. I was just being annoying.

We have a weird upwelling of very cold water just offshore, and it
makes the city cool to cold almost all year, and only the hardiest of
lunatics swim in the ocean here.

Is Amsterdam above sea level? I grew up in New Orleans, at about -3
feet. My kitchen floor here is 365 feet above sea level, so we don't
worry much about tidal waves.

Amsterdam is several meters below sea level

shows you the water column. NAP is an international standard.
I worked on those systems, there are huge pumps pumping the water outside the
dykes.
If ever electricity failed (like it was not there), the city would flood.
Considering the size of the area, after some rain incredible amounts of water
need to be pumped out.
This water level is sensed in hundreds of places, and needs to be precise within
centimeters for agriculture (a lot of farm land is within the dikes).
