Seasonal context
Rainfall and the growing season in Gatchina
August has the highest average precipitation (100 mm); February has the lowest (44 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.

Local growing check
Before choosing winter melons for Gatchina
- August is the wettest month in the rainfall grid, averaging about 100 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 winter melons
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 20°C (68°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
- Check the local overnight forecast before planting out. Delay planting or keep protection ready if frost is forecast, even after the historical last-frost date.
- 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 young wax gourd or a fully mature storage crop
Allow substantial vine space or a support designed for the weight of developing fruit. Provide sun, drained fertile soil and moisture through active growth. A small greenhouse may fill with foliage before a large-fruited cultivar reaches maturity.
For storage, wait for the cultivar's mature rind and waxy surface, handle carefully and keep only sound fruit. Young hairy-melon types are a different harvest choice and may not develop the same mature coating.
What to record this season
Did the selected variety reach its intended young or storage-harvest stage within the warm season? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates
Allow substantial vine space or a support designed for the weight of developing fruit. Provide sun, drained fertile soil and moisture through active growth. A small greenhouse may fill with foliage before a large-fruited cultivar reaches maturity.
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
This calendar uses frost-relative offsets as a starting point. Winter melons are timed from 5 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Gatchina.
The median frost-free season here is 149 days, against 110 to 140 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.

Growing winter melons in Gatchina
Can I grow winter melons in Gatchina?
The calendar estimates a planting window, not a guarantee of success. August is the wettest month in the rainfall grid, averaging about 100 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
When might winter melons be ready to harvest in Gatchina?
The estimated period is 1 Sep - 30 Nov, based on 110 to 140 days from the modeled planting date. Cultivar, planting material and growing conditions can change this interval; check the plant as well as the calendar.
Why is there no model planting window for winter melons in Gatchina?
The air-temperature model does not find the target soil warmth within the allowed planting period. This is not a measurement of your bed. Check soil temperature, the cultivar and local growing advice before choosing an outdoor date or a protected growing method.
How much frost will winter melons tolerate?
Check the named variety and local forecast before exposing young growth. The catalog cold-damage figure is a reference, not a guarantee: plant age, acclimatisation, wind and the duration of a freeze affect damage.
