Immediate Forecast - Espinho

Valid: This Morning 11 AM through Tomorrow 3 AM

Key Messages

• Temperatures will rise to around 11°C by early afternoon, then gradually fall overnight toward 4°C.
• Light rain is possible tonight after 8 PM, but timing and occurrence remain uncertain due to inconsistent model guidance.
• Winds will remain light through the day, increasing tonight and peaking near 27 km/h around 3 AM along the coast.
• No immediate hazards are expected, though brief gusts near 27 km/h may affect exposed coastal areas in the early morning hours.

Current Conditions & Near-Term Outlook

As of 10:11 AM, Espinho is experiencing 8°C under mostly clear skies. Over the next few hours, temperatures will rise steadily, reaching around 11°C by 1 PM. Skies will become partly cloudy through midday, then gradually clear again by 5 PM. Winds will remain light and variable, with no significant impacts expected during daylight hours. Conditions will remain dry through the afternoon, with no precipitation observed or indicated in real-time IPMA observations from surrounding stations.

This Afternoon

From noon to 6 PM, expect mild and generally pleasant conditions with temperatures near 11°C and increasing sunshine as clouds break up. Winds will stay below 15 km/h, favoring light west to northwest flow. Any lingering high clouds will dissipate by late afternoon, leading to a mostly clear sky by 6 PM. No precipitation is expected during this period—chances remain near 0%. The evening commute will be dry and calm, with temperatures holding steady around 11°C through 8 PM.

Tonight Outlook

After 8 PM, cloud cover will increase rapidly, becoming overcast by 9 PM. There is a 60% chance of light rain beginning around 8 PM, lasting through the overnight hours until about 1 AM. Total accumulation is expected to be light—around 1.8 mm if rain occurs—but model guidance shows low agreement, with one recent run predicting no rain at all. Therefore, confidence in precipitation occurrence and timing is reduced. If rain does develop, it will be brief and localized, with no significant impacts expected.

Winds will shift to the east-southeast after 8 PM and gradually increase, with gusts reaching up to 27 km/h near the coast between 2 AM and 3 AM. These gusts may briefly affect loose objects or tree limbs in exposed areas but are not expected to cause damage. Temperatures will begin a slow decline after 4 PM, falling to around 6°C by midnight and reaching 4°C by 3 AM.
