Not sure if it is a Calima or just a hazy day. Relative humidity is quite high. For sure not much vitamin D at the moment but given a choice prefer here then UK this w/e

Wind is from the East, humidity a bit low and dust a bit higher than normal but nowhere near as bad as 11 days ago.

Sorry it is only available on my LAN. It is a Raspberry PI Zero in the cupboard/shed on my Balcony with an Enviro+ card and some software I wrote myself, that can be found here: https://github.com/nophead/EnviroPlusWeb

Thanks anyway.

Just am into anything wx wise and that looked interesting to me. Almost went starry eyed for a minute.

Cheers

I believe it is spelled Calima and is a local weather phenomenon where a high pressure in the Sahara desert causes hot winds from the East laden with sand.

The Calima arrived late yesterday evening and overnight the wind has increased to gusting 45kts which is blowing the sea spray somewhat!

Every now and then a wave of Dust sweeps past. Mayhem out in the streets with rubbish and the odd large dustbin out for a stroll all by its self. Due to all pass by later today. Airports were shut for a while but open againat the moment. Fire in Gran Canary started overnight. Humidity is low.

Oh dear, we were planing to go there on Wednesday for the Lamb.

A big globe off a street light a few doors away has blown off and was rolling around in the footwell outside our door. Lots of the big green bins seem to have blown over.

Can someone explain, as I can't work it out!
So Calima's hit us a few times a year. And they must deposit many tonnes of sand, surely in the thousands. As not only on the Canaries but the surrounding Atlantic ocean. So this must have been going on for millions of years. Tenerife is approx. 7 million years old.
How is it possible that there can be any sand left in the Sahara Desert.

Interesting question. I think it is because the desert is huge and isn't as old as the Canaries.

I do know there are large blond sand dunes on Fuerteventura that have blown in from the Sahara.

The forecast I saw had a 10% chance of rain and we just had some! That might clean the air a bit.

According to AEMET winds decreasing and third wave of calimas due tonight, but probably the worse has passed.
