Apologies if this is in the region of grandmas and egg sucking but the kind of weather we're getting at the moment is likely to mean more difficulties in starting. Condensation and damp overnight settles on all the wires and connections, if they're not fully tight or have become dirty and corroded then it takes far more electricity to turn the starter and fire the engine. Batteries will be in a lower state of charge through use of wipers, lights, heaters etc so all in all it's not surprising that vehicles have starting problems. When I did car maintenance classes (not quite as far back as when we had to have a chap walking in front waving a flag) we were advised to spend a Saturday morning at 3 month intervals making sure the battery was topped up to the correct level with distilled water, if necessary put it on charge to make sure it was in peak condition, the terminals had been cleaned and lightly abraded with some wet & dry paper to ensure a good connection, after refitting the terminals and connectors smeared with water repellent grease which you can get from Halfords and similar places. All wires from distributor to plugs were wiped clean of moisture and oily residue which attracts and retains water, plug tops cleaned off and again all very lightly smeared with water repellent grease or WD40. This used to take no more than an hour or so and virtually eliminated any starting difficulties for months and the battery lasted far longer.
Rather than turning the key and letting the engine turn over and over first thing, you could try just giving it a quick turn over for less than a second, turn the ignition off for 15 or 20 seconds and then try again. The first 'burst' helps to break the sticky oil film in the engine block, reduces the resistance and allows oil to splash out of the sump onto moving parts for lubrication and protection. It also means you're not draining the battery and the second attempt usually starts the car with no problems. Obviously, you don't turn lights, heaters, wipers, radios etc on until the car is running!
