no ric, it's not unusual at all. what we get now is 'la gota fría', a few days of pretty bad weather in a row the island always gets at some point towards the end of the summer. last year it was the last week of august and luckily after that the weather was gorgeous again until mid november.
I'd like to think that the worst is over now, but it does look like the unstable weather situation is going to continue for another few days. hopefully not too much rain anymore! and then also hopefully a dry closing party weekend, depending on where you look it should get better from tuesday PM onwards.
also, for those still coming in the next few days - as soon as the sun comes out it gets hot instantly. unfortunately the water temperature already has gone down considerably, but it's definitely still warm enough for a swim. just bring a jumper for the evenings - night time temperatures are a bit lower now.
