Guingamp faces a day of persistent clouds and brisk winds. Temperatures remain stable, with humidity and wind shifts marking the forecast. Evening brings clearer skies but a noticeable drop in temperature.
Guingamp starts the day under a thick layer of clouds and a steady breeze. Any hope for late-summer sun fades as the sky stays gray and the wind keeps temperatures from rising. Humidity creeps up, and the weather feels unsettled throughout the day.
The morning is chilly, with temperatures between 12 and 13°C. Winds from the west and west-southwest reach up to 15 km/h, and gusts can hit 20 km/h. There is a short break in the clouds, but it doesn't last. By midday, the temperature climbs to 17°C, and the wind shifts northwest, picking up speed with gusts close to 25 km/h. Humidity drops a bit, but the unsettled feeling remains.
On September 8, 2026, a yellow wind warning was in effect for Côtes-d’Armor, including Guingamp, due to expected strong gusts.
The afternoon brings more of the same. The sky stays mostly cloudy, turning even darker by mid-afternoon. Temperatures level off between 17 and 18°C. The wind, now from the north-northwest, holds steady at 10 to 15 km/h, but gusts become stronger and more frequent, reaching 30 to 35 km/h. Humidity rises early in the afternoon, then drops again later.
As evening arrives, the weather finally starts to shift. The sky clears a bit, and temperatures hold at 18°C. The wind continues from the northwest at 15 km/h, with gusts up to 30 km/h. Over the next few hours, skies clear further and temperatures fall quickly, dropping to 14°C and then 11°C by late evening. The wind weakens and shifts from west-northwest to southwest, while thin high clouds move in overnight.
Night brings little change. Temperatures settle around 10 to 11°C, with a slight chill before dawn. Winds stay moderate, between 5 and 10 km/h, and gusts ease to 10–15 km/h. High clouds linger, with only brief spells of full overcast. Humidity, already high at nightfall, climbs even more as morning nears.
According to Ouest-France, wind gusts in Guingamp on September 8 reached up to 60 km/h, and the following morning brought drizzle and high humidity, highlighting a period of particularly unstable weather in the region.
Thursday looks similar. The day starts at 10°C under high clouds and heavy humidity. The sky brightens a little by late morning, but thick clouds return in the afternoon. Temperatures reach 19°C by evening. Winds, light from the southwest at first, pick up to 15 km/h with gusts up to 30 km/h later in the day.
Weather like this is typical for Brittany in early September, when the Atlantic brings quick changes and stubborn cloud cover. The mix of steady temperatures, shifting winds, and high humidity shapes daily routines, from commutes to evening plans. For those watching regional events—like the recent surge in concert attendance in Barcelona reported earlier—Guingamp's weather is a reminder that local conditions can be just as unpredictable as the headlines. The current forecast calls for flexibility, as Brittany's climate continues to mix clouds, wind, and sudden drops in temperature.
