Spring in numbers — this week’s figures: Week 41 of 2026
5–11 October 2026 · 24–30 Rabi' al-Akhir 1448 AH. 10 figures about spring in the Kingdom from an analysis of satellite imagery (land greenness only), each with a sentence ready to quote, its source and a permanent link that does not change.
An estimate from satellite imagery using DataPulse's methodology, not an official statistic.
This week’s figures were frozen on 5 October 2026 (24 Rabi' al-Akhir 1448 AH) from the satellite image dated 3 October 2026 (22 Rabi' al-Akhir 1448 AH), and do not change after that. The latest available image is dated 4 October 2026 (23 Rabi' al-Akhir 1448 AH); its figure shows under each figure that differs, for information, not for quoting.

Spring area in the Kingdom
7,443km²
The visible spring area in the Kingdom was 7,443 km² in the latest satellite image (dated 3 October 2026 (22 Rabi' al-Akhir 1448 AH); the clearest image in 26 September – 3 October 2026 · 15–22 Rabi' al-Akhir 1448 AH), of which 3,275 km² was strong spring.
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): area: 7,385. For information only; quote the frozen figure above.
The spring area in the Kingdom shrank by 1,212 km² (−14.0%) compared with the image of 25 September 2026 (14 Rabi' al-Akhir 1448 AH), 8 days earlier: from 8,655 to 7,443 km².
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): change: −1,241, percentage: −14.4. For information only; quote the frozen figure above.
Spring in the Kingdom is now wider than in 19 of the last 24 years in October. The “now” area in this comparison is 7,616 km² in one-kilometre squares, which is how the tool compares with past years.
The spring area in Jazan Region was 2,388 km² in the latest image (dated 3 October 2026 (22 Rabi' al-Akhir 1448 AH)), the second-widest spring among the regions.
Compared with past years: spring in Jazan is now wider than in 21 of the last 24 years in October.
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): area: 2,352. For information only; quote the frozen figure above.
The spring area in Makkah Region was 1,011 km² in the latest image (dated 3 October 2026 (22 Rabi' al-Akhir 1448 AH)), the third-widest spring among the regions.
Compared with past years: spring in Makkah is now wider than in 13 of the last 24 years in October.
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): area: 1,004, wider than in: 15. For information only; quote the frozen figure above.
1,452 km² in the Kingdom turned green recently: it became spring within the last 16 days (since 17 September 2026 (6 Rabi' al-Akhir 1448 AH)), and was not spring in the image before that.
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): newly green: 1,540. For information only; quote the frozen figure above.
Widest spring in October since the start of the record
26,159km²
The widest spring in October since the start of the image record (2002) was in October 2024 (Rabi' al-Awwal – Rabi' al-Akhir 1446 AH), with an area of 26,159 km² (the month’s average in one-kilometre squares).
The satellite detected spring around 36 named destinations (a rawdah, faydah, shaib, wadi, qa’a or khabra) in the latest image (dated 3 October 2026 (22 Rabi' al-Akhir 1448 AH)), within about five kilometres of each, with neighbouring points counted as one destination.
Latest image (4 October 2026 (23 Rabi' al-Akhir 1448 AH)): destinations: 38. For information only; quote the frozen figure above.
The same method as the «Where is the spring?» tool
Source: our analysis of open satellite imagery (NASA MODIS through the NASA GIBS service), with the same method as the «Where is the spring?» tool: the satellite measures the greenness of the land cell by cell (about half a kilometre), and we compare it with the colour of the same land when dry, so what has clearly increased is classified as “spring”, then “strong spring”. What is called “starting to green” is not included in the spring area here.
What we exclude: farms, built-up areas and permanent greenery (land cover from ESA WorldCover) and the surroundings of villages and hijrahs, and we count a cell as spring only if a second, independent satellite confirms it.
The image: the clearest image of the last eight days, so its date may precede the freezing day by some days. The “previous image” is the one from the period before it.
Comparison with past years: one image per month since the start of the record in one-kilometre squares, marked the same way; we calculate the “now” area in the same squares (so it differs slightly from the map figure), then count in how many past years the same month had a smaller area than now; a month whose area is small in most years is not compared. Details in “This year compared with past years”.
Freezing: we freeze each week’s figures at the first site build of that week and keep them in a file that is never rewritten, so the figure behind the permanent link does not change. In the current week the figure from the latest image shows under a figure if it differs, for information, not for quoting.
Checking: every figure on these pages is recalculated automatically from the saved week file at every build, and any difference stops publication. The measured accuracy is in “How accurate are we?”.
Limits: the figures describe what the satellite detected; they are not a recommendation of a destination or a guarantee of its condition on the ground. We publish no meteorological information of any kind.
Downloads: the CSV and JSON files are the frozen week files; their statements are in Arabic, and the values are the same as on this page.
