Winter Weather Prep in Saudi Arabia: Cold Nights, Rain Safety and Driving
Winter in the Kingdom brings welcome relief from the heat, but it also brings chilly nights, sudden downpours and slippery roads. A little preparation at home and in the car goes a long way. This guide covers safe heating, rain and flood precautions, wet-weather driving and where to get official alerts.
Quick answer
Short answer: Follow the National Center for Meteorology (NCM) early warnings or its Anwaa app before trips. Stay away from valleys and flash-flood areas when rain is forecast, as Civil Defense advises. At home, use heaters safely: keep them clear of curtains, and if you use gas or kerosene heaters, ventilate well and fit carbon monoxide detectors near bedrooms, as the Ministry of Health recommends.
Key takeaways
- Official alerts: NCM publishes active early warnings by region on its early-warning page.
- Valleys: Civil Defense urges people to avoid flash-flood areas and valleys and not to swim in them.
- Carbon monoxide: MOH says heaters that burn gas, kerosene, coal or wood emit carbon monoxide.
- Oil-filled heaters: MOH says they run on electricity and don’t produce harmful gases.
Start with official forecasts and alerts
The single most useful winter habit is checking the forecast before you set off. NCM’s early-warning page lists active warnings by region and governorate, with colour-coded alert levels and start and end dates.
NCM also offers the Anwaa app for forecasts on your phone. If you’re planning a desert camp, a mountain drive in the south-west or a long highway trip, check both the day before and the morning you leave.
This autumn has already been wetter than usual in places. In September, NCM forecast above-average October rainfall across most regions, and indicated rain could continue into November. Our post on the October rain outlook explains what that seasonal forecast means.
Tip
Turn on notifications in the Anwaa app and keep it on the home screen of every driver in the family. A two-second check can change your route.
Rain and flash flood safety
Flash floods can form quickly, even when it isn’t raining where you are. Water from distant hills can run down a dry valley (wadi) with little warning.
Ahead of thunderstorms in November 2025, the General Directorate of Civil Defense urged the public to stay in safe locations, avoid areas prone to flash flooding and valleys, and not swim in them. Take that advice seriously every time NCM issues a rain warning for your area.
Warning
Never drive or walk into flowing water in a valley or underpass. Water depth and current are very hard to judge, and vehicles can be swept away. Turn back and wait for the flow to stop.
Some practical habits help:
- Camping and picnics: don’t set up in a valley bed or at the foot of slopes, and leave early if rain is forecast.
- Children: keep them away from pools of rainwater, drainage channels and valley edges.
- Home: clear roof drains and balcony outlets before the rainy weeks, and move valuables off the floor in ground-level storage.
Driving on wet roads
The first rain after a long dry spell can make roads especially slick. Plan for slower journeys and give yourself extra time.
Wet-weather driving routine
1
Check before you go: look at NCM warnings for your route, not just your city.
2
Slow down early: reduce speed and roughly double your usual following distance.
3
Lights on: use dipped headlights in rain, fog or dust so others can see you.
4
Avoid flooded dips: take a longer route rather than crossing standing or flowing water.
5
Brake gently: avoid sudden braking or steering, which can cause skids.
6
Pull over safely if visibility drops: stop well off the road, away from valleys, and wait.
Before winter, check your tyres, wipers and lights. Worn tyres and old wiper blades are the most common weak points on a wet day.
Keeping warm safely at home
Nights can turn cold, especially in the north and in high areas. The Ministry of Health’s home heating guidance splits heaters into two groups: electric ones, and those that burn gas, kerosene, coal or firewood.
| Electric heaters | Gas or kerosene heaters | |
|---|---|---|
| Examples | Oil-filled, fan, panel, beam | Gas and kerosene heaters |
| Carbon monoxide | Oil-filled heaters produce no harmful gases | Burning fuel emits carbon monoxide |
| Key safety step | Automatic shut-off; keep clear of curtains and furniture | Good fresh-air ventilation |
| Maintenance | Check the cord; plug directly into the wall | Check the heater every year |
| Extra protection | Don’t cover the heater | Carbon monoxide detectors near bedrooms |
MOH also advises against running electric heater cords under the heater or carpets, and against using extension connections. Don’t burn charcoal or firewood in a closed room. MOH lists both among the fuels that emit carbon monoxide, a gas you can’t see or smell.
Your winter checklist
Use this list in the next few weeks, before the coldest nights and heaviest rain arrive.
Winter-ready home and car
- Anwaa app installed and NCM early-warning page bookmarked
- Roof drains and balcony outlets cleared
- Heaters checked: automatic shut-off, sound cords, clear space around them
- Carbon monoxide detector fitted near bedrooms if you use gas or kerosene heating
- Tyres, wipers and lights checked on every family car
- Warm layers and a torch in the car for long trips
Winter is also the busy season for outdoor events. If you’re heading out, our guide to Riyadh Season 2026 covers what has been confirmed so far.
