Thursday 18 June starts on a slightly messy note for many drivers, even though the day turns warmer later. The Met Office says the UK sees outbreaks of rain easing in the northwest, hill and coastal fog with drizzle in western and southwestern areas, and brighter conditions elsewhere before the southeast turns humid later with showers that could become thundery. Its London and South East forecast is similar: a cloudy start with some drizzle, especially along southern coastal districts and hills, before brighter spells develop later. That makes this the sort of morning when clear glass, a checked route and a calmer start matter more than usual.
Trust today's route check, not yesterday's habit
National Highways says planned full closures on England's motorways and major A roads generally run from 8pm to 6am, and it warns that early-morning journeys may still be affected by closures that started the evening before. That matters on an ordinary weekday because the familiar route can look different before sunrise. National Highways also says the A3 southbound approach to M25 junction 10 at Wisley is scheduled to close overnight on Thursday 18 June from 10pm to 5:30am, so if you use that corridor later today or need an early Friday start, it is worth checking the latest closure list before you travel.
Damp starts expose small preparation gaps fast
A cloudy or drizzly morning does not sound dramatic, yet it quickly exposes all the easy-to-ignore little issues. Windscreens smear more easily, mirrors stay dull for longer and a low washer bottle becomes more annoying when drizzle and grime sit on the glass. GOV.UK says drivers are responsible for making sure a vehicle is safe every time they drive, so the sensible move is to fix the basics before the trip begins rather than after the first roundabout.
- Clean the windscreen, side glass and mirrors so drizzle, haze and reflected glare are easier to manage.
- Check the wipers clear properly and top up screenwash if the bottle is getting low.
- Make sure lights work and lenses are clear if the car has been outside overnight.
- Check fuel or battery range against the full trip, including any diversion around overnight works.
- Move loose bags, charging leads and bottles away from the driver footwell and front seats.
- Keep your phone cable, work pass, medication and water within easy reach before you set off.
Drive for the visibility you have now
The Highway Code guidance on adverse weather is useful here because it focuses on what the driver can actually see and stop for. A bright or very warm afternoon forecast does not remove the need to drive carefully through the part of the morning that is still cloudy, damp or a bit misty. If the road surface is patchy, the screen is smearing or traffic is reacting late to a closure, leave more room, keep your speed sensible and avoid turning an ordinary commute into a rushed one.
Keep useful safety kit inside the cabin
The things you may want first should stay inside the passenger area rather than under shopping bags or in the boot. Water, a torch, a charging cable or power bank, a high-visibility vest and essential medication all become more useful when traffic slows or a diversion adds time to the journey. Fast access matters more than perfect packing.
The same applies to an escape tool. A compact window breaker and seatbelt cutter should stay inside the cabin rather than buried under other gear. A single tool works well for one main car, while a two-pack is practical if you want one near the front seats and another in a second vehicle or closer to passengers.

Use five calmer minutes well
Thursday morning 18 June is not a severe-weather commute, but it is a commute that rewards margin. Drizzle at dawn, damp glass, humid air later and closure-aware route planning are enough reasons to slow the start slightly and do the simple checks properly. If the day brightens quickly, that is fine. The safer choice is still to prepare for the conditions you actually have when you open the car door.
