Climate at a glance
Flores Weather Essentials
Atlantic control
Rain, Wind and the Azores High
Ocean moderation
The Atlantic limits extreme heat and cold, so winter is mild compared with continental climates and summer rarely becomes persistently hot.
Rain in every month
Showers occur year-round, with wetter and stormier patterns generally from autumn through early spring. Waterfall flow responds accordingly.
Azores High
This semi-permanent pressure system influences North Atlantic weather, but its movement does not guarantee settled conditions over the island that shares its name.
Atlantic depressions
Passing low-pressure systems can bring strong wind, heavy rain, rough sea, poor visibility and transport disruption.
Humidity and cloud
Moist air produces fast-changing cloud, condensation and fog, especially on the central plateau and windward slopes.
Sun after rain
Clear breaks can arrive quickly, but a bright coast does not prove lakes, trails or flight approaches are free of cloud.
Season by season
Spring, Summer, Autumn and Winter
Spring: March–May
Typical conditions are mild, often around 15–17°C, with rain, wind and four to six hours of sunshine. Flowers and strong waterfall flow reward flexible travelers.
Summer: June–September
The warmest and relatively driest period commonly reaches about 19–25°C, with six to seven sunshine hours and brief showers still possible.
Autumn: October–November
Temperatures often remain near 17–20°C while rainfall, swell and Atlantic storm risk increase. Trails may become muddier and days shorten.
Winter: December–February
Typical air temperatures are around 13–16°C, but strong wind, frequent rain and rough sea make it feel cooler. Snow is rare and limited to unusual high-elevation conditions.
Best overall period
June through September usually provides the broadest opportunity for hiking, pools, events and flights, not a guarantee of clear weather.
Quieter shoulder season
Late spring can provide flowers, waterfalls and lighter demand, provided plans can move around cloud and rain.
Microclimates
Coast, Plateau, Waterfalls and Sea
Santa Cruz and east coast
The airport side may have different wind and cloud from the west. Flight operations depend on local approach conditions, not the forecast at lodging.
Fajã Grande and west coast
High cliffs enhance waterfall scenery and can trap orographic cloud. Afternoon light and swell vary independently.
Central lakes
The 600–700-meter plateau is cooler, windier, wetter and foggier than sheltered lowlands. Visibility can disappear within minutes.
Morro Alto
At 914 meters, the summit area is exposed and may require warmer layers, rain protection and willingness to turn back.
Trails and streams
Rain falling out of sight upstream can raise crossings and soften ground. Official closure and local conditions override a general forecast.
Marine conditions
Wind, tide and Atlantic swell decide boats, diving and pools. Sea risk can remain after the sky clears.
Plan well
Practical Flores Weather Tips
Pack layers
Carry a light insulating layer, breathable waterproof shell, sun protection and shoes that grip wet stone and mud.
Check several zones
Compare airport, coast, plateau, marine and trail information instead of relying on one island-wide symbol.
Keep a flexible day
Move lakes, hikes, boat trips and waterfall viewpoints to the best available window.
Protect transport connections
Leave margin around flights and Corvo trips; wind and low cloud can change operations.
Avoid floodwater
Never cross a swollen stream, enter a waterfall pool after heavy rain or stand below unstable cliffs.
Use indoor alternatives
Museums, churches, cafés, craft shops and village drives can preserve a day when highland visibility is poor.
Questions travelers ask
Flores Weather FAQ
What is the best time to visit Flores?
June through September usually offers warmer and relatively drier conditions, while late spring can be quieter and flower-rich. Every season needs flexibility.
Does it rain a lot on Flores?
Yes. Rain can occur in every month and is one reason the island is exceptionally green and rich in waterfalls.
Is Flores warm in winter?
Winter is mild rather than warm, often around 13–16°C, with wind, rain, humidity and rough seas making it feel cooler.
Will the crater lakes be visible?
Not always. Fog frequently covers the central plateau, so check live conditions and return later if the coast is clear.
Can weather disrupt flights and boats?
Yes. Wind, low cloud, rough sea and operational conditions can delay or cancel service, so protect onward connections with buffer time.
