Weather in Granada in September

Prime time. September is about as good as Granada gets. Highs average 27.2 °C, lows 17.1 °C, and rain falls on 4 days — nothing in the month is working against you.

September ranks 2 of 12 in Granada. Only May scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 4 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 September day reached 38.3 °C and the coldest night fell to 11.2 °C, and the wettest single day dropped 38 mm — roughly 146% of the month's rain in one day.

September is moderately variable: 1 mm in the driest year against 66 mm in the wettest, around an average of 26 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 7.5 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: 4.9 °C cooler than August, with October dropping another 4.8 °C. The first week and the last are not the same trip.

Daylight in September

12.5 hours of daylight, losing 1.2 hours across the month. That is between Granada's extremes of 14.7 and 9.6 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 27.7 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

September in Granada versus nearby

If Granada is one option among several, the nearby comparison is worth making. Málaga is close enough to be a coin toss — 2 °C cooler, the same number of rain days. Sevilla is the weaker option in September — 5.8 °C warmer, the same number of rain days.

So: September is effectively as good as it gets here — 1 points behind May, which is inside the margin where the weather stops being the deciding factor and price starts being it.
