Weather in Alexandria in September

A good month. September is a solid month to be in Alexandria. Highs average 32.7 °C, lows 22.3 °C, and rain falls on 0 days — nothing in the month is working against you.

September ranks 10 of 12 — near the bottom of Alexandria's year. April is the month that works, and the swing between the two is 50 points, which is a different holiday rather than a slightly better one. Worth keeping in perspective: September is the weakest month of Alexandria's year and it is still a perfectly good one. The downside here is small.

Rain is not a factor worth planning around this month. Pack for 32.7 °C days and 22.3 °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: 5 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest September day reached 40.1 °C and the coldest night fell to 18.7 °C.

September is dependably dry, and that reliability is the point: across the twenty years measured, the wettest September on record still only managed 5 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Septembers brought 3 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 11.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 62%.

How September sits in the year

The month is on the way down: 1.7 °C cooler than August, with October dropping another 3.4 °C. The first week and the last are not the same trip.

Daylight in September

12.4 hours of daylight, losing 0.9 hours across the month. That is between Alexandria's extremes of 14.2 and 10.1 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 27 °C in September — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

September in Alexandria versus nearby

If Alexandria is one option among several, the nearby comparison is worth making. Cairo is the weaker option in September — 3.8 °C warmer, the same number of rain days. Port Said is a better bet in September — 6.1 °C cooler, the same number of rain days.

So: September is a compromise. April is 24 points better and is what Alexandria is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
