How accurate are weather forecasts for silver coast and porto early/mid November

The weather forecasts are not very good even a week out. We have had a run of very rainy weather the last couple of weeks, though. The good news is that even when it rains, it’s unusual for it to be an all day affair. It’s usually brief showers only. And, when the forecast says rain, it could be one shower in the middle of the night.

All that said, the weather patterns have been changing the last year or so, so there is really no way to predict.

Even if it says daily rain, don’t expect it to be raining all. It may rain while you’re sleeping or periodically during the day. It may also only be a drizzle. Could it be true you’ll experience downpours each day, yes, but I doubt it will be even close to that. Take a parka and umbrella and enjoy your trip.

I don’t find any weather forecast, at home or abroad, to be very accurate.

Thank you. I hope that's true. One website I was on was very detailed like each day saying what time it would rain. And it was mostly during the day and some at night
