As an amatuer engineer, I have nothing but respect for professionals who really know their stuff.

1Steve put up a graph that shows 500mm for the year to date; which seems more like reality to me.
I can only say that in my area, flooding and washed out roads are the result of a lack of maintanance to drainage systems.
It hasn't rained like this in so long that no one was paying attention anymore.

The graphs 1Steve put up are monthly values.
500mm in a year would be the driest parts of the country. In the North more like 1000mm+
As an example in Spain, Vigo gets around 1700mm rainfall per year.

The record for mainland Portugal is 220,0 mm of rainfall in 24 hours from 1977.

I wrote year to date; that is, from Jan 1.
So yes, a month.
We got less than 500mm per year for 8 of the last 10 years according to my own at home measurements.

In Hong Kong we get around three metres of rain per year so big storms and typhoons are commonplace. In the mid 1990s I was photographically recording the construction of our first public golf course, which is situated on an island that the British navy used to use for shelling practice. Basically the holes are shaped, drainage and irrigation laid and then a sand cap of about 18 inches covers the whole thing and springs of grass are scattered on top and worked in by a simple machine that is dragged behind a fat tyred vehicle. During the course of construction we had a massive storm blow in that dumped one metre of rain over a weekend. The grass on the course was bedding in nicely at this point but when the storm arrived it did all sorts of damage. The 11th is a par three played uphill, and when I get there with my camera gear following the storm I found the 11th green had been reduced to a large pile of sand in a pond located next to the tee. Right now the weather in the Algarve feels more like the weather Hong Kong, which is somewhat depressing.

It won't happen very often Sportpix. According to one of my Portuguese friends, he can't remember this happening in his lifetime and he's in his mid 50's.

Been very wet here, wind not too bad, so no damage.

And I have to navigate dirt tracks over streams this morning, to get into Ourique. Not looking forward to it.

Don't worry!
Soon it will be dry and sunny again.
Every day.

Sorry, the image I had seen was December 2025.

You were also right; I only looked at the bottom graph (January 2026).

Looks like the jet stream is on the move finally, it will buckle and move further north over the next week, given us a break from this awful weather.

I was just watching a German weather forecast for next week and it is predicting very heavy rain for Portugal, Spain, Italy and Morroco

Please tell me this is a wind up 🙏

On tv this morning (uk) it had Portugal as having more rain in these next few days.

If anyone is interested the Spanish Meteorological Agency have a really good weather simulation available for free. I have used it for many years and it is pretty accurate for forecasts up to about 48 hours.
Not that difficult to use even if you don't understand Spanish.

Most of the heavy rain in the coming days will fall in the Central/Northern regions with the sunny Algarve escaping the worst with the exception of perhaps Friday
Below is the forecast for tomorrow midday. Cannot wait for Saturday as the sun is forecast for the North. Don't remember what it looks like.

I also recommend the BBC weather charts and the Jetstream charts,
