Weather in Lárisa in September

A good month. September is a solid month to be in Lárisa. Highs average 29.7 °C, lows 18.2 °C, and rain falls on 6 days — nothing in the month is working against you.

September ranks 5 of 12 in Lárisa: past the worst of the year but short of April, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29.7 °C days and 18.2 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 14 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest September day reached 40.9 °C and the coldest night fell to 9.6 °C, and the wettest single day dropped 38 mm — roughly 79% of the month's rain in one day.

September is moderately variable: 6 mm in the driest year against 114 mm in the wettest, around an average of 48 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 6.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 56%.

How September sits in the year

The month is on the way down: 5.2 °C cooler than August, with October dropping another 5.9 °C. The first week and the last are not the same trip.

Daylight in September

12.5 hours of daylight, losing 1.3 hours across the month. That is between Lárisa's extremes of 15 and 9.4 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 32.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

September in Lárisa versus nearby

If Lárisa is one option among several, the nearby comparison is worth making. Volos is a better bet in September — 4.4 °C cooler, 1 day more rain. Thessaloníki is a better bet in September — 2.3 °C cooler, 1 day more rain.

So: September works, with April the better month by 12 points if the dates can move. If they cannot, nothing here should stop you booking.
