The weather is looking pretty average over the long range forecasts and may well influence us on whether we hire a car or not. I appreciate long range forecasting is a dark art but even this coming weekend looks to be possibly raining!
How was/is the weather?

Just hire one anyway – the geography means you can have a snowball fight on Teide then swim in 20 degree water an hr later. Or chase the rain, sit above the clouds – whatever…
Get out, explore the island – you’ll be go smacked at what is outside the resorts

The inlaws went on Tuesday apparently it’s very agreeable

Have been a few times meself even when it rains its not cold and grey and miserable like it is in the UK. Can always find a beach bar and prop that up for an hour or so
