Weather and Climate in Al-Kharj
This page brings together the live picture for Al-Kharj now — temperature, feels-like, wind, dust and air quality — with an hour-by-hour outlook and a full seven-day forecast, followed by a grounded guide to how the local seasons behave across the farmland.
The climate of Al-Kharj is hot desert (Köppen BWh): long, fiercely hot and dry summers, a short mild winter with cold nights, and dusty spring winds. Lying around 435 m above sea level — lower than Riyadh itself — it tends to run a fraction warmer than the capital by day, while the wide irrigated farmland lifts the local humidity a little above the open desert.
Al-Kharj receives only about 100 mm of rain a year, almost all of it between November and April. Peak-summer afternoons reach about 44 °C while mid-winter days sit near 20 °C, with overnight lows around 27 °C in July and 6 °C in January, when the open farmland can cool sharply under a clear sky.
That climate gives Al-Kharj a clear agricultural rhythm: a long, hot growing season sustained entirely by irrigation, a brief mild winter that is the pleasant heart of the year, and short, dusty shoulder seasons when the spring winds sweep across the open basin.
Summer
Summer in Al-Kharj is long and severe, with peak highs around 44 °C, very dry air and relentless sun. The green, irrigated farmland holds a little more moisture than the surrounding desert, so afternoons can feel marginally closer; field work and outdoor activity are best confined to the early morning and the cool of the evening.
Winter
Winter is mild and sunny by day, with afternoons near 20 °C, and cold by night, with lows around 6 °C and the occasional light frost over the open fields on the clearest, calmest nights. It is comfortably the most pleasant season, and the best time for the area’s farms and date groves.
Spring & Autumn
Autumn is a brief, welcome cooling into clear, settled days. Spring brings the year’s most active rain and the dust storms that sweep the open basin, hazing the sky and dusting the crops before the air clears again.
Rain Probability
Rain in Al-Kharj is scarce and seasonal, confined almost entirely to the cool season and spring; summer is effectively rainless. When systems arrive they can be brief but locally heavy, and because the basin is flat and the ground dry, water can pond quickly across fields and roads after a strong storm. The hourly and daily panels above show the live chance of rain.
With an annual total of only about 100 mm, individual storms matter, and a single wet spell in spring can deliver much of the year’s rain. Check the precipitation-probability figures above before travelling out to the farmland on an unsettled day.
Wind and Humidity
Al-Kharj shares Najd’s very low humidity, though its extensive irrigated farmland nudges the local moisture a little higher than the open desert, especially around dawn. The chief weather hazard is dust: northerly winds, strongest in spring, raise dust storms across the flat basin that cut visibility and lift the air-quality reading sharply.
The live wind speed, gusts and direction in the dashboard above update through the day, alongside feels-like and dew point — the readings that explain why a humid morning over the fields can feel quite different from a dry, windy afternoon.
Planning around the weather
Planning around Al-Kharj’s weather is simple: treat the long summer as a heat-management season — lightweight clothing, sun protection, steady hydration, and outdoor work kept to the cool ends of the day — and pack a warm layer for the cold winter nights over the open farmland. On dusty spring days, those sensitive to dust should limit time outdoors and check the air-quality reading first.
The most agreeable time in Al-Kharj is the cool season from roughly November to March, when warm, sunny days and cool nights make the farmland and date groves at their best.
