How hot is your street

How much heat is on your street#

Type a street. You get the surface mean around its addresses, the hot share, the band it falls in, and the nearest measured park — all from 29 June 2026, around 12:02.

How Bucharest streets compare

On half of the 3,530 measured streets, the mean passes 49.1°C. The threshold for “hot” is 50°C.

The hottest street is Intrarea Binelui: 54.0°C, across 22 addresses. The coolest is Aleea Ștrandului Tei: 39.1°C, across 20 addresses. And Smârdan, in the Old Town, has 53.1°C across 72 addresses.

The numbers come from a single clear midday, 29 June 2026, around 12:02. It is surface temperature, not air: asphalt and sheet metal read far above what you feel in the shade.

What the degrees mean#

Every street, park and map cell is coloured by its mean surface temperature, in degrees Celsius; the bands are the same everywhere. It is what the asphalt felt at midday, not the air.

Band	Mean	What it looks like
Cool	under 44°C	The big parks sit here: Cișmigiu 42.8°C, Herăstrău 41.3°C.
Warm	44–47°C	Sector 1, the coolest sector, sits here, at 44.9°C.
Hot	47–50°C	The street median sits here, 49.1°C, with Mihai Bravu at 48.0°C.
Scorching	50–52°C	Vasile Lascăr is here, at 51.1°C.
Searing	52–54°C	Smârdan (53.1°C) and the hottest street, Intrarea Binelui (54.0°C), sit here.
Furnace	above 54°C	Strada Hărniciei is here, at 54.2°C.

A pixel is 30 metres, from a native 100-metre signal: one pixel holds roof, street and tree at once. That is why the page talks about the zone's heat, not your door's.

The 50°C threshold is this analysis's cut: on this page, “hot” means pixels of at least 50°C. Every ranking sits beside the raw mean.

How the number is made#

Each street takes its heat from around its addresses: 50-metre discs around every point in the index, clear pixels only, no clouds. The mean is the mean surface temperature; the share is the fraction of pixels of at least 50°C.

The day is 29 June 2026, around 12:02: a Landsat 9 pass with not a cloud above the city — 100% of pixels are cloud-clear. Of 13 summer passes under 20% cloud, we read 5 near-clear candidate scenes pixel by pixel and took the hottest.

A street with under 3 addresses or under 20 clear pixels gets no number; rankings keep only streets with at least 20 addresses. 1,348 streets stayed unmeasured — they show as such, not as zero.

Limits: the satellite's thermometer measures the skin of the surface, not the air — some pixels pass 60°C when the shade, per the ERA5 reanalysis, peaked at 35.9°C that day. A pixel mixes everything it catches: roof, street, tree. And it is a single June midday: by evening, the city looks different.
