Alexandroupoli weather by month, at a glance

The whole year in one picture — sky, rain, humidity, temperature and travel score. Click any band to jump to its full chart.

Each stripe is one measure across the whole year, stacked so a single day reads top to bottom. The sky band runs overcast grey on top down to clear blue at the base — more blue means sunnier — followed by the rainfall curve, the humidity band, a temperature strip that tints each stretch of the year by how warm its average high is, and the travel-score line at the foot. Scan straight down any date to read that day across every measure at once; the score climbs highest around late April to mid July.

Humidity comfort

DryComfortableHumidMuggyOppressiveMiserable

Share of days at each humidity comfort level, based on the dew point — the measure that tracks how muggy it actually feels.

Humidity comfort is graded by the dew point — the temperature at which the air would be fully saturated — because it tracks how muggy it actually feels far better than relative humidity does. A low dew point feels dry and crisp; a high one feels sticky and oppressive no matter the reading on a humidity gauge.

In Alexandroupoli, how humid it feels changes dramatically over the year.

The more humid part of the year lasts 4.6 months, from around May 21 to October 8. The muggiest month is August, when the air feels humid, muggy or worse about 72% of the time.

The most comfortable stretch runs from around October 9 to May 20, and January is the most comfortable month — the air is dry or comfortable 100% of the time.

Wind

Average wind speed through the year, banded into plain-language speed zones so a number reads as 'breezy' or 'calm' without knowing the scale.

This is the average sustained wind speed at the standard 10 metres above open ground — the steady flow a weather station reports, not the sharper gusts that come and go, which can run half again as fast. It's the number that says whether a place is generally breezy or calm.

Across the year, average wind speed in Alexandroupoli is typically light breeze, near 16 km/h, and varies moderately with the seasons.

The windier part of the year lasts 5.8 months, from around Oct 7 to Apr 2. The windiest month is February, averaging about 18 km/h (light breeze).

The calmer part of the year runs from around Apr 3 to Oct 6, with June the calmest month at about 12 km/h.

Average hourly UV index in Alexandroupoli

LowModerateHighVery highExtreme

Modeled clear-sky UV for every hour of every day — when in the day sun protection actually matters.

The whole year hour by hour: each column is a day, each row an hour, and the color is the modeled clear-sky UV index — the midday peak scaled down as the sun sits lower in the sky. Darker overlays mark night, lighter ones the civil-twilight hours around sunrise and sunset.

UV falls off far faster than brightness as the sun drops, so even in June the burn window is concentrated in the middle of the day: about 8.5 hours a day reach index 3 (protection recommended), and 5 hours reach 6 or more. Mornings and late afternoons stay comparatively gentle year round.

Solar energy

Average daily shortwave solar energy reaching the ground, banded into brightness zones so the number means something at a glance.

Solar energy is how much sunlight actually reaches the ground each day, measured in kilowatt-hours per square metre (kWh/m²) — the combined effect of how long the sun is up, how high it climbs, and how much cloud gets in the way. It's the raw fuel a solar panel has to work with: for scale, 1 kWh/m² a day is dim and wintry, while 7+ is desert-bright.

Alexandroupoli receives about 4.4 kWh/m² a day of solar energy on average — bright — with a clear seasonal swing between 1.6 and 7.2 kWh/m².

The brighter stretch of the year lasts 6.1 months, from around Mar 24 to Sep 24. The brightest month is July, averaging about 7.1 kWh/m² (intense).

The dimmest month is December, down near 1.6 kWh/m² — roughly 77% less than the July peak.
