I have just checked the weather for Tenerife for the next few days and it ranges between 20 and 21 degrees, I am in a dilemma as to what sort of clothes to pack as I have my heating at home set to 23 so wondering if I will be cold in just a summer dress or shorts and t-shirt. This past week I noted it was 10 degrees out there with rain and wind so I will bring a warm set of clothes but I am wondering what the ratio of summer to winter clothes I should pack (want to travel light if possible, so leaving snow clothes at home!)
