  • All year: cannot be answered, because usable light has not been recorded here.

Not full sun or shade. How much usable light actually arrives across a day, and whether the spot ever dries.

Something growing here

The moss end does not work for growing things on a day like this, and how long it stays wet is why.

  • How long it stays wet is14h over24h against at most 10h

    Roots and foliage sitting wet kill more plants than the wrong hardiness zone does.

Confidence medium (60%). Enough to point in a direction, not enough to buy against.

What this answer was built from
  • Use
    Something growing here
  • Place
    The moss end
  • Weather
    Temperate maritime, mild, grey, damp (scenario shape) (from a published source)
  • Method
    A whole day in September, traced against the scene rather than read at one hour
  • How well this place is described

    Mapped
    1. Quick
    2. Mapped
    3. Annotated
    4. Measured

    Shade, sky view and daily light are computed from real geometry rather than assumed. This is the rung at which the product starts telling you things you did not already know.

    It cannot answer who can see in, and it cannot tell you whether the heights it is using are the real ones.

    To reach Annotated

    • Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
    • Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
    • Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

    What that buys: The privacy question, and a check on the geometry. Most inferred heights are wrong by enough to matter, and a photograph settles it in a minute.

    Everything that was checked
    • Quick A place on the earth: Los Angeles (demonstration), with a time zone, which is what makes an hour an hour.
    • Quick Somewhere to read: 1 spot marked. A reading is a height at a place, and moving it moves the answer.
    • Mapped The things in the way: 2 objects drawn. The house counts, and so does the neighbour's.
    • Mapped What is underfoot: 1 of 1 readings sit on a mapped surface.
    • Mapped Where the property ends: Drawn, so the product can tell you when the cheapest fix stands on someone else's land.
    • Annotated Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
    • Annotated Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
    • Annotated Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.
    • Measured Heights off a tape: 1 of 2 objects are measured. The remaining 1 are this product's own inference, so no figure here is a survey figure yet.
    • Measured Something checked against the day: Nothing has been checked against a real afternoon. The model is unopposed, which is not the same as being right.

    What to measure next

    Ranked by how far the answer moves, not by a checklist
    1. 1Who can actually see inSit in the chair

      Sit where you actually sit and look around. Mark the one window or path you can see a person from. Until one exists, privacy is a question we are not answering rather than one that is fine.

      This is not a refinement. Nothing can answer this question until somebody marks it.

      Currently assuming: nobody is overlooking this. Tested across one confirmed observer changes the whole privacy answer.

    2. 2What you are looking atSit in the chair

      Mark the direction of the view worth keeping. Without it, every screening recommendation is optimising against nothing.

      This is not a refinement. Nothing can answer this question until somebody marks it.

      Currently assuming: no view is being protected. Tested across one corridor changes what screening is worth doing.

    What the place is doing at 6:34pm in September

    Temperate maritime, mild, grey, damp (scenario shape).

    What it feels like

    comfortable

    64°F

    Felt temperature · 34 on the reporting scale

    It feels about what the thermometer says, roughly 64°F.

    What is doing it

    • How much sky is overhead

      1.7°
    How this was worked out
  • Air
    63.6°F from Temperate maritime, mild, grey, damp (scenario shape), scenario (from a published source)
  • Radiant
    64.7°F mean radiant temperature
  • Method
    Six-directional radiation integration, then ASHRAE operative temperature (from a published source)
  • Direct sun

    in sun

    9.9 W/m²

    Beam reaching this point · 100 on the reporting scale

    Direct sun is on this spot right now.

    How this was worked out
  • Sun

  • Traced
    100% of the beam reaches this point
  • Glare

    difficult

    out of 100

    The sun is 28 degrees off the line of sight and low enough to stay in peripheral vision.

    How this was worked out
  • Facing
    241deg (assumed, not measured)
  • Sun off the line of sight
    28deg
  • Assumed
    Which way the seat faces has not been set, so glare is estimated from the open direction. (assumed, not measured)
  • Privacy exposure

    Unanswered

    No observer has been placed yet. Privacy is a question about who can see in from where, and until one is marked there is nothing to answer.

    Wind

    light

    1.2 mph

    Wind at the seat · 6 on the reporting scale

    Wind here is light.

    How this was worked out
  • Reference
    9.2 mph at 10 m from Temperate maritime, mild, grey, damp (scenario shape), scenario (from a published source)
  • At seat height
    1.2 mph before shelter
  • Shelter
    0% removed by what stands upwind
  • View

    Unanswered

    No view worth keeping has been marked, so there is nothing to weigh a screen against yet.

    Surface heat

    comfortable

    67.2°F

    Surface temperature · 9 on the reporting scale

    The surface is running about 67°F.

    How this was worked out
  • Surface
    The lawn
  • Method
    Absorbed shortwave against air temperature, flattened by air movement (from a published source)
  • Wetness

    Drying time against the open · 21 on the reporting scale

    Still air here; moving air does a surprising amount of the drying.

    How this was worked out
  • Drying rate
    0.000 in/hour here
  • Method
    Penman combination equation on the radiation and air actually reaching this spot (from a published source)
  • Light after dark

    Artificial light is not doing anything at this hour.
