Weather and Climate in Helwan
At about 40 m above sea level and with around 650,000 residents, Helwan carries a hot desert climate. Use the live readings and forecasts on this page together with the seasonal guide below to plan around the city’s weather with confidence.
The climate of Helwan is hot desert (Köppen BWh). In practical terms that means a hot desert climate where the Nile meets the sand — long hot summers, brief mild winters, and dusty spring Khamsin winds. The single biggest influence on day-to-day conditions is the long, sun-dominated dry season set against a short, concentrated wet season around December through February.
Across an average year Helwan receives only about 25 mm of precipitation, almost all of it in the cooler months. Temperatures vary widely between the seasons: peak summer afternoons typically reach about 36 °C while mid-winter days hover near 19 °C, with overnight lows of roughly 22 °C in July and 9 °C in January.
That climate translates into a clear daily and yearly rhythm in Helwan: heat concentrates in the afternoon while the wide diurnal swing — close to 14 °C between the summer peak and dawn — brings real relief after dark. Reading the live values at the top of this page alongside the seasonal guide makes it easy to judge whether a given day is typical for its season or an outlier.
Summer
Summers are long, hot and dry, with daytime highs in the mid-to-high thirties and barely a drop of rain from May to October. The dry desert air makes the heat fierce but more bearable than the humid coast. In Helwan, expect daytime highs around 36 °C at the height of summer, easing to near 22 °C overnight. Humidity is generally low, so the heat is dry rather than muggy.
Winter
The cool season is the most comfortable time in Cairo: sunny, dry afternoons and crisp evenings, with only the occasional passing shower. Through the coolest weeks, Helwan sees highs near 19 °C and lows around 9 °C. Frost is essentially unknown, and the cool season is the most comfortable stretch of the year.
Spring & Autumn
The shoulder seasons swing between pleasant and dusty: autumn is calm and clear, while spring can be abruptly hot and hazy when the Khamsin arrives. For Helwan, spring and autumn are pleasant windows, with mild days and warm evenings — though the March through May, the Khamsin season can bring hazy skies and a sharp, short-lived rise in temperature.
Rain Probability
Rain in Helwan is scarce and highly seasonal. The wet months run December through February, and outside that window measurable rainfall is rare — summer in particular is essentially rainless. The hourly and daily panels above show the live chance of rain for the next week.
Because the annual total is so small — around 25 mm concentrated into a handful of months — individual rain events stand out. When systems do arrive around december through february, they can be brief but locally heavy, occasionally enough to pond water on streets that are otherwise bone dry. Check the precipitation-probability figures above before heading out in the cool season.
Wind and Humidity
Winds in Helwan are shaped by Egypt’s broader desert and Nile circulation. The hot, dust-laden Khamsin is the signature wind, sweeping up from the south mainly in March through May, the Khamsin season; it is the chief cause of hazy, reduced-visibility days. The live wind speed, gusts and direction in the panel above update through the day.
Humidity is generally low, which keeps the summer heat dry; it climbs mainly during and after the brief winter rains. Together, wind and humidity explain why two days with the same temperature can feel so different in Helwan — which is why the dashboard above tracks feels-like, dew point and gusts alongside the headline reading.
Planning around the weather
If you are planning around Helwan’s weather, the rhythm is straightforward: treat the summer as a heat-management season and the brief winter as the only time you really need to plan for rain. Lightweight, breathable clothing, sun protection and steady hydration are the essentials for the long warm season, with a light layer for cooler winter evenings.
The most agreeable times to be in Helwan are the cool season and the calmer stretches of spring and autumn, when temperatures are moderate and the skies are usually clear.
