Morning coffee, through the year. The morning chair is open for morning coffee 6:00 AM to 10:00 AM, May to September. It opens at different hours April and October. Shut November to March. 7 months open, 5 shut, 0 unanswered.JanFebMarAprMayJunJulAugSepOctNovDec7months open

The morning chair is open for morning coffee 6:00 AM to 10:00 AM, May to September. It opens at different hours April and October. Shut November to March.

  • November to March: shut for morning coffee. What it feels like is what stops it.
  • April: open 8:00 AM to 10:00 AM.
  • May to September: open 6:00 AM to 10:00 AM. What it feels like is what closes it.
  • October: open 9:00 AM to 10:00 AM.

The shut months are shut for one reason: what it feels like. That is the thing to change if you want the season longer, and it is a different job from making the open months better.

The morning chair for Morning coffee. October 30, 2026 at 4:01 AM, America/New_York. Now on this date. Confidence low. Cause: What it feels like is what stops it.

Twenty minutes, first light, nobody looking.

Morning coffee

The morning chair does not work for morning coffee right now, and what it feels like is why.

“No” means the model does not support this use under the conditions being read. The controlling limits are listed below.

  • Past the limit What it feels like is about 36°F — 18°F under (at least 54°F)Estimate: Worked out, but at least one input was assumed rather than measured.

    The air is 44.4°F. It feels about 8.4 degrees cooler than the air, near 36°F.

    Early sun is usually the point, not the problem.

Still unanswered:Privacy exposure
Why it is unanswered
  • Privacy exposure. 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.

What would change this. This would change if what it feels like were measured rather than estimated, or if privacy exposure were measured.

Confidence low (35%). Treat this as a starting hypothesis, not an answer.

What next here

Testing a change

3 of 8 milestones. One thing is still in the way of privacy, sightlines and screening advice.

  1. Getting an honest answer3 of 4 done
    • Placed on the earth — done. The sun is in the right part of the sky for this address.
    • A spot to read — done. 1 spot is being read.
    • What stands in the way — done. 3 things are drawn, so the shade is worked out rather than assumed.
    • Who can see in — not done. Privacy is the most common reason a terrace goes unused, and it cannot be answered without knowing which windows look at it.
  2. Testing a changeyou are here0 of 2 done
    • A change tested — not done. Testing a change before buying it is the cheapest part of the whole exercise.
    • A forecast checked — not done. A forecast nobody goes back and checks is a guess with a date on it.
  3. Proving it well enough to spend money0 of 2 done
    • Corrected against reality — not done. After a couple of rechecks the model can be corrected against this specific garden.
    • Photographed — not done. A photograph is what turns a drawing somebody sketched into a drawing somebody can check.
  1. Mark the windows that look at this spot

    Being overlooked is one of the most common reasons a good terrace goes unused, and it is the one reading here that cannot be inferred from anything else.

    a tap per windowneeded for privacy, sightlines and screening advice
  2. Get this place to Annotated

    A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions. Right now: Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place. What is missing: 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.

    3 things left
  3. Test a change before you buy anything

    The plan is good enough to ask what a screen, a tree or a canopy would actually do here — including the ones that turn out to be a waste of money.

    a few minutes, nothing bought
3 more things worth doing here
  1. Add a second spot and compare the two

    One spot gives a verdict; two give a reason. Most of what is worth learning here is why one corner works at six and the other never does.

    one tap, then read across
  2. See how this spot changes through the year

    A terrace that works in July can be unusable in September for reasons that have nothing to do with temperature. The same geometry read in four seasons is the cheapest insight here.

    a read, nothing to enter
  3. Photograph the spot and mark what is in shot

    A photograph is what separates a drawing you sketched from a drawing somebody else can check. It is also how heights get corrected without a ladder.

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

Shade, sky view and daily light are computed from the geometry on this plan. Unmeasured dimensions remain estimates, not verified measurements.

Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place.

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: A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions.

Everything that was checked
  • Quick A place on the earth: Boston (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: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.
  • Measured Heights off a tape: 2 of 3 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.

    Mark it on the plan

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

October 30 · The morning chair Schematic: A shape of the facts, not a picture of a particular date or a measured outline.
  • Works (solid)
  • Tight (lined)
  • No (pale, edged)

The sun reaches the morning chair at 7:16 AM. The morning chair loses the sun at 5:38 PM.

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 morning chair is open for morning coffee 8:30 AM to 10:00 AM.

About 1.5 hours in October.
