Круг Таро, Рейки и Магии

I'm planning a ten-day trip to Tenerife in late July, and I'm trying to make an itinerary that leaves room for the weather rather than treating every day the same. The seaside temperatures look inviting, but I keep reading that a drive into the mountains can feel very different, especially if we stay out after sunset. We would like a few beach days, alongside a walk near Teide and a couple of shorter trips to towns away from the resort area. I have been reading tenerife weather in july and august while deciding what clothes and timings make sense, but I would appreciate advice from people who have actually made a similar trip. Would you commit to a set date for the upland outing, or keep that day flexible until the forecast is clearer? We are happy to leave before breakfast, although we do not want to spend the entire holiday racing from place to place. I am still trying to judge whether light layers are enough for an evening at higher altitude or if a proper jacket is useful. If you have planned a July visit, how did you balance heat, driving time, and rest days? A realistic day-by-day rhythm would be more useful than a packed checklist.
