Heat in Blouberg

Summer 2025/26: the ground in Blouberg reached about 35 °C on clear mornings. That is the ground (roofs, roads, soil), not the air. The coolest summer since 2014.

Land surface temperature is how hot the ground itself is: roofs, roads, bare soil and leaves, as a satellite sees them from above. Landsat passes at about 10 in the morning and sees only through clear skies. It is not the air temperature a weather station gives: on a sunny day the ground is often 10 to 20 degrees hotter than the air, and hard, dark, dry surfaces heat up most while trees, grass and water stay cooler.

What it is not: not the afternoon peak, not the night, not the air you feel in the shade, and not a reading at any one house. A month with clouds rests on few clear looks.

Every summer since 1987

Each summer (December to February, named by the year it ends) on clear mornings. Bars start at 32 °C, not zero. Darker: Landsat 8 and 9 (from 2014); lighter: Landsat 5 and 7. A gap is a summer seen too little.

“Clear looks” is how many times the average 240 m patch of the place was seen through clear sky that month. Under one, part of the place was not seen at all, so the figure leans on the part that was.

How we worked this out

Landsat 5 to 2011, Landsat 7 to bridge the gaps, Landsat 8 and 9 from 2013: different satellites pass at slightly different times, so compare summers within the same years first.

What we changed: we kept only the clear land cells (no cloud, cloud shadow, snow or water, with a margin round each cloud), read them at 480 m, and averaged them over each 2026 ward each month; larger places are the sums of their wards.
