Weather in Pátra in May

Prime time. May is about as good as Pátra gets. Highs average 26.2 °C, lows 15.2 °C, and rain falls on 6 days — nothing in the month is working against you.

May is the highest-scoring month of the twelve. The nearest rival is April, and the month at the other end of the year is August.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: 6 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest May day reached 40.2 °C and the coldest night fell to 7.7 °C.

May is moderately variable: 12 mm in the driest year against 59 mm in the wettest, around an average of 27 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 7.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 68%.

How May sits in the year

The month is on the way up: 5.2 °C warmer than April, and June adds another 5.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in May

14.2 hours of daylight, gaining 0.9 hours across the month. That is between Pátra's extremes of 14.8 and 9.5 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 19.3 °C in May — swimmable, but it takes a moment to commit. The sea peaks at 26.6 °C in August and bottoms out at 15.5 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, November is the trade worth considering — 14 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

May in Pátra versus nearby

If Pátra is one option among several, the nearby comparison is worth making. Kalamata is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Volos is close enough to be a coin toss — 4.4 °C cooler, the same number of rain days.

So: May is the answer for Pátra. If it is booked out or priced out, April is the next best thing at 2 points behind, and August is the month to keep off the shortlist.
