Current Conditions & Near-Term Outlook

As of 05:20 UTC, Gondomar is under increasing cloud cover with temperatures near 8°C and light winds. Over the next several hours, conditions will remain dry with no precipitation expected. Cloud cover will build through the early morning, reaching near-total overcast by 07:00 UTC. From 09:00 to 11:00 UTC, skies are likely to clear quickly, with mostly sunny conditions developing by mid-morning. This break in clouds will coincide with the warmest part of the day, with temperatures reaching 10°C by late morning and holding through early afternoon.
