Aljezur's weather is Atlantic first: mild winters, dry summers, and wind that can howl when summer Nortada fires across the region. Use this page as a planning sketch, not a guarantee—town, Arrifana cliff, and inland valley microclimates differ. Check IPMA before you travel.
What shapes Aljezur’s climate?
Latitude and ocean moderate extremes — rarely freezing in town, rarely stagnant heat like inland Alentejo. Topography channels wind: north and northwest winds are common; south swells and east (Levante) conditions happen but are less dominant than on the south coast. Fog and low cloud can hug the coast in summer mornings then burn off by noon.
Surfers care about wind + swell + tide together — how to read surf conditions complements this weather primer. For month-by-month waves, best time to surf Aljezur goes deeper on sessions.
Month-by-month weather overview
Figures below are typical ranges for the Aljezur / west Algarve coast — rounded from long-term climate patterns. Rain days = days with meaningful showers, not drizzle minutes.
| Month | Avg high °C | Avg low °C | Rain days (approx) | Sunshine hrs/day | Sea temp °C | Wind notes |
|---|---|---|---|---|---|---|
| January | 15 | 8 | 10 | 5 | 15–16 | Atlantic lows, gusty |
| February | 16 | 8 | 9 | 6 | 15–16 | Variable; some big swell |
| March | 17 | 9 | 8 | 7 | 15–16 | Building spring sun |
| April | 19 | 10 | 8 | 8 | 16–17 | Showers still common |
| May | 21 | 12 | 5 | 9 | 17–18 | Nortada begins to appear |
| June | 24 | 14 | 2 | 10 | 18–19 | Dry; afternoon breeze |
| July | 26 | 16 | 1 | 11 | 19–20 | Nortada frequent |
| August | 28 | 16 | 1 | 10 | 20–21 | Peak wind & tourists |
| September | 26 | 16 | 3 | 8 | 21–22 | Warm sea; first autumn storms |
| October | 23 | 14 | 7 | 7 | 20–21 | Swell builds; mixed skies |

| December | 16 | 9 | 10 | 5 | 17–18 | Stormy spells; cool water |
Takeaway: Wettest stretch November–February; driest June–August; warmest sea late summer into September; most reliable afternoon wind mid-summer.
Microclimates: town vs beach vs inland
- Aljezur town — a few degrees warmer on calm nights than exposed Arrifana car park; fog less often than right on the cliff.
- Arrifana / Ponta da Atalaia — windier, cooler “feels like” in July–August even when the thermometer says nice.
- Monte Clérigo — open bay; morning glass possible; afternoon sea breeze.
- Amoreira — estuary mist mornings; wind funnels off the river valley.

The Nortada — what summer surfers should know
The Nortada is a thermally driven north/northwest wind common on the Portuguese west coast in summer. It often starts late morning and strengthens through afternoon, onshoring many beaches and chopping the surface — tough for beginners, sometimes fun for shortboard practice if you accept texture.
Strategy: dawn patrol or evening glass-offs; sheltered corners on certain tides; check windguru / surfline with local knowledge. Summer surfing Aljezur expands on seasonal tactics.
What to pack by season
Winter (Dec–Feb): rain jacket, layers, warm mid-layer for evenings, 4/3mm or 5/3mm wetsuit for surf, boots on cold days. Hat and gloves if you feel the cold — water drops to mid-teens °C.
Spring (Mar–May): mix of T-shirts and fleece; 3/2mm wetsuit** transitioning** to short arm late May depending on you; sunscreen — UV builds fast.
Summer (Jun–Aug): sun protection (hat, reef-conscious sunscreen), windbreaker for cliffs, 3/2mm or even spring suit August for long sessions; beach shade if kids involved — surfing with kids in Aljezur.
Autumn (Sep–Nov): best all-round clothes — shorts + jacket; 3/2mm or 4/3mm late autumn; watch first big swells — surf safety Portugal before you charge.
Rain and storms
November–February delivers frontal rain — sometimes horizontal on the cliffs. Flooding in river lowlands is occasional; respect road closures. Lightning is rare at the coast but not impossible — leave the water.
Planning your trip around weather (not Instagram)
Shoulder seasons (April–May, September–October) balance temperature, crowds, and swell. July–August is reliable for sun but crowded and windy afternoons. January is quiet and powerful if you are experienced — winter surfing Aljezur.

Is Aljezur hotter than Lisbon in summer?
Often cooler daytime “feels like” on the coast due to wind; Lisbon inland bakes more.
When does the sea feel swimmable without a wetsuit?
High summer for short dips; surfers usually still want rubber for long sessions — personal tolerance varies.
Does it ever snow?
Extremely rare at sea level; Serra de Monchique hills occasionally see light snow — not a Aljezur town problem.
