Current Conditions & Near-Term Outlook

As of 05:20 UTC (06:20 local time), Valongo remains dry with temperatures around 6°C under increasing cloud cover. Over the next few hours, skies will become mostly overcast by 08:00, but no rain is expected during the morning commute. Temperatures will hold steady near 6–7°C through sunrise, then begin a gradual rise through midday. By 10:00, clouds will break quickly, leading to a mix of sun and clouds through the early afternoon with temperatures reaching 10°C.

The chance for precipitation remains low but increases slightly from mid-afternoon onward. Between 16:00 and 20:00, there is a 10–18% chance of a brief, light shower. Any shower would be isolated and short-lived, with little to no accumulation expected. These scattered showers are not expected to affect all areas, and long dry periods will persist between them.

Temperatures will begin to fall after sunset, dropping from 7°C by 18:00 to around 5°C by 20:00. Skies will clear rapidly through the evening, leading to a mostly clear and calm night. No precipitation is expected after 20:00. The remainder of the night will be dry and quiet, with lows near 5°C by early Friday morning.

There is no risk of freezing or wintry weather at this time. Any moisture from potential showers will not persist long enough to create slippery conditions.
