in May.
A warm, very dry month: the 6th warmest and the 5th driest of the year. Meets the pleasant-weather rule
Long-term climate patterns, not a forecast for a particular trip.
May is a warm month in Rosetta: daytime highs average 26.1°C and nights cool to about 17.8°C. By daytime temperature it is the 6th warmest of the 12 months.
Rain is very rare: less than 1 mm falls in a typical May (the 5th driest of the 12 months). Daylight, from sunrise to sunset, lasts about 13 h 44 min on an average May day.
The nearest other city in this atlas is Idkū (15 km away). In May its highs average 27.5°C, 1.4°C warmer than Rosetta, with 1.1 mm of rain.
Among the 107 cities listed in Egypt, Rosetta ranks 105th of 107 for the warmest May highs and joint 79th of 107 for the driest May (rainfall, lowest first). The mean May high of those 107 cities is 33.1°C; Rosetta is 7.0°C cooler than that mean.
From May to June, average highs rise by 2.5°C to 28.6°C, and monthly rainfall stays under 1 mm.

Read the numbers correctly
Climate, not a promise.
These patterns help compare months. They cannot tell you the weather on a specific day of your trip.
Sources, method and limitsHow these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Rosetta) is explained once on the Rosetta year overview and on the Sources, method and limits page.
