Temperature-based estimate. Cairo has no dependable frost season.
These dates do not account for rain, humidity or waterlogging. Check the local growing season,
especially in monsoon climates, before treating this window as a planting recommendation.
Rainfall check: the wettest month is November (about 17 mm), and the driest is
August (about 0 mm).
Compare all months and check the limitations before choosing the season.

Each window is a planning range. Check the forecast, soil and cultivar before planting; a later date is not automatically safer in hot or wet conditions.

Seasonal context
Rainfall and the growing season in Cairo
November has the highest average precipitation (17 mm); August has the lowest (0 mm). Compare this pattern with the planting windows and your water supply.
During wetter months, check that beds and containers drain after heavy rain. During drier months, plan how you will keep seeds and new transplants watered. Monthly averages can hide long dry spells and intense storms; they do not show soil moisture, humidity or this week's weather.
Frost-free does not mean every month is suitable. In tropical and monsoon climates, rainfall, heat, drainage and the cultivar can set the practical growing season. Match the temperature window to these conditions and check advice from a local grower before buying planting material.

Local growing check
Before choosing lettuce for Cairo
- Average daytime highs reach at least 32°C in May, June, July, August, September. Plan establishment and flowering with local heat advice. This screen highlights hot months; it is not a crop-specific damage threshold or a heatwave forecast.
- November is the wettest month in the rainfall grid, averaging about 17 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
The temperature and rainfall tables on this page show the underlying climate estimates. How these suitability checks work · Record what happens in your garden.
Before you plant lettuce
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 4.5°C (40.1°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- In a frost-free climate, check seasonal rainfall, humidity and heat before planting. A month with suitable average temperatures can still be too wet, dry or hot for this crop.
- Harden off plants raised indoors: gradually expose them to outdoor light, wind and temperature before their final move into the bed.
- Use the maturity range on your seed packet when choosing a variety. Cold, short days and transplant stress can make harvest later than the calendar estimate.
Choose loose leaves or a whole head before sowing
Lettuce has shallow roots. Keep the seedbed evenly moist, then check it regularly in dry weather; a dry surface can stop emergence even when deeper soil remains damp.
Heat and water stress encourage bolting and bitter leaves. In a hot season, compare locally suitable varieties and a cooler position instead of assuming that any frost-free week is suitable.
Sow modest batches so that the crop does not all mature together. Record which variety and sowing produced usable leaves before the weather changed.
Growing in a container
Loose-leaf types are useful in containers. Leave room to reach individual plants and keep drainage clear; a small pot needs frequent moisture checks.
What to record this season
Which sowing gave usable leaves before bolting, and was it a head or leaf harvest? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Frost-relative timing needs a dependable seasonal frost date. Cairo has no such date in this record, so this page compares monthly temperatures with the crop's model range instead. Local wet and dry seasons, day length and cultivar requirements still need a separate check.
The model uses a growing-temperature band for lettuce between 4.5°C (40.1°F)40.1°F (4.5°C) and 25°C (77°F)77°F (25°C) — and in Cairo that is October to April, 7 months of the year, taken from this location's own monthly averages. The planting window begins near the start of this period. The catalog estimate is 45 to 60 days from planting to maturity under suitable conditions.

When should I plant lettuce in Cairo?
The temperature-based window is 1 Oct - 15 Nov. Cairo has no dependable frost season: October to April have monthly averages inside the model range for lettuce. Check seasonal rainfall, heat and cultivar requirements before planting.
When might lettuce be ready to harvest in Cairo?
The estimated period is 15-30 Nov, based on 45 to 60 days from the modeled planting date. Cultivar, planting material and growing conditions can change this interval; check the plant as well as the calendar.
How much frost will lettuce tolerate?
Protect tender growth from frost and wait for suitable growing warmth. The catalog cold-damage figure is a reference, not a guarantee: duration, wind, plant age and acclimatisation affect damage.
