When the one chair is open for morning coffee

Rings run from 4 am at the centre to noon at the edge.

The one chair is open for morning coffee 6:00 AM to 7:00 AM, August to October. Shut November to July.

  • November to July: shut for morning coffee. What it feels like stops it in 6 of those months and wind in most of the rest.
  • August to October: open 6:00 AM to 7:00 AM. Wind is what closes it.

The shut months are not shut for the same reason. What it feels like closes 6 of them and wind closes most of the rest, so a single change will not open the year — it will open part of it.

6:33 PM·September
September 14 · The one chair

The evidence behind this whole day is thin, so nothing on the strip is marked out as worse than the rest. The shape of the day is still the model’s best reading; the confidence in it is low, and it stays low until something it needs is measured.

The one chair is open for morning coffee 12:00 AM to 8:00 AM.

About 8 hours in September, and wind is what closes it.

Morning coffee

The one chair is on the edge for morning coffee right now, and wind is why.

  • Wind is4.5 mph over12.3 mph against at most 7.8 mph

    Cold air moving early is what sends people back inside.

  • Wetness is10 over50 / 100 against at most 40

    Dew is the actual reason the morning chair is unusable, not temperature.

Confidence low (41%). Treat this as a starting hypothesis, not an answer.

What this answer was built from
  • Use
    Morning coffee
  • Place
    The one chair
  • Weather
    Coastal Mediterranean, dry summers, salt air (scenario shape), scenario (from a published source)
  • Method
    Traced geometry and radiation at this hour, measured against what this use needs
  • 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.

    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: 3 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: 1 observer marked.
    • Measured Heights off a tape: 0 of 3 objects are measured. The remaining 3 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

    Nothing you could measure would change this answer. What is limiting this place is real, not uncertain.

    What the place is doing at 6:33pm in September

    What it feels like

    comfortable

    67.2°F

    Felt temperature · 39 on the reporting scale

  • Privacy exposure

    screened

    5

    out of 100

    Nothing marked here has a usable line to this seat.

    • The flat opposite

      +3.0
    How this was worked out
  • Observers
    1 marked
  • Method
    Eye-to-eye rays traced against the scene, weighted by how much each observer matters
  • Wind

    gusty

    12.3 mph

    Wind at the seat · 61 on the reporting scale

    Nothing upwind is doing much; this spot gets close to the open wind speed.

    How this was worked out
  • Reference
    10.3 mph at 10 m from Coastal Mediterranean, dry summers, salt air (scenario shape), scenario (from a published source)
  • At seat height
    12.3 mph before shelter
  • Shelter

    About 54% of the view worth keeping is already gone from this seat.

    The bay
  • Method
    Rays sampled across each corridor's angular window

    Surface temperature · 16 on the reporting scale

    The surface is running about 74°F.

  • Method
    Absorbed shortwave against air temperature, flattened by air movement (from a published source)
  • Wetness

    dries-fast

    Drying time against the open · 7 on the reporting scale

    Sun and air movement here are enough to dry the surface at an ordinary rate.

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