Our estimate, from CMA GRAPES's forecast made early this morning (19.3° after taking
out its usual 0.5° cold lean here), narrowed by what NZWN has reported so far and by how much
it usually still climbs after this hour. Replayed on 19 past days (967 station-days): ranges it gave about 30% happened about 30% of the time. Its most likely range came true about a third of the time at 08:00, two thirds at 14:00 and nearly always by 17:00.
The market price is the crowd's view; neither is advice.

where the high landed on 64% of days
On dates near this one, this station's daily maximum fell between 12:00 and 15:00 local on 64% of 129 days, most often around 13:00.
The five-year mean curve is highest at 14:00 — that is when the average day is warmest, which runs later than the typical day's own peak.

Each bar is the middle half of days (25th–75th percentile) under
that sky, with a tick at the mean; the centre line is this station's normal for the date.
Sky state is the mean cover across the hours the day warms (09–15 local), not a
single reading. An indicator, not a cause — where a sky state is rare it
tends to arrive with the system that made it rare, so a large figure is usually the
weather pattern showing through the cloud rather than the cloud itself. Greyed rows are
not separable from normal.

Each bar is the middle half of days (25th–75th percentile) for
that direction, with a tick at the mean; the centre line is this station's normal for the
date. Direction is where the wind came from. An indicator, not a cause -- a
direction arrives with a weather system, and it is the system you are seeing. Greyed rows
are not separable from normal. ⚠ “now” is the latest single observation,
while the history buckets whole days (09–15 local averaged), so today may still
finish in a different sector.

Each morning the site picks the model that has missed least here lately and takes out
its usual lean; this is that forecast, made before the day's heating, beside what the station recorded.
Over all 30 scored days: a typical miss of 1.0°, within a degree on
53% of days.

the best model is not the same everywhere, and the median gap between a station's best and worst model is 1.2°C. A wide disagreement means
the models have found different weather, not that the average of them is right.

Typical miss is how far off the model usually is, in either direction — lower
is better. Warm / cold is which way it leans: a model can be accurate on average and
still run consistently warm here. Within 1° is how often it landed inside a degree.
Scored against what this station actually recorded, over 38 days.

Climatology is what this station actually recorded on this date across five years of IEM
observations, bucketed on the rounded whole degree exactly as the market settles.
It is a base rate, not a forecast — it knows nothing about today's weather,
and the market does. Where the two differ, the market usually has the better information.
Market column sums to 100% and climatology to 100%.
