Seasonal context
Rainfall and the growing season in Peterhof
August has the highest average precipitation (90 mm); February has the lowest (38 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 melons for Peterhof
- August is the wettest month in the rainfall grid, averaging about 90 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 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 21°C (69.8°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 a melon that can ripen in your available warmth
Provide sun, warmth, fertile soil and consistent moisture with drainage. Decide whether vines will trail or climb before planting; hanging fruit may need support separate from the vine.
Check the supplier's ripeness indicators for the cultivar. Do not assume that every melon slips from its stem, changes colour or develops a strong scent in the same way.

Why these dates
Provide sun, warmth, fertile soil and consistent moisture with drainage. Decide whether vines will trail or climb before planting; hanging fruit may need support separate from the vine.
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.
This calendar uses frost-relative offsets as a starting point. Melons are timed from 4 weeks before that frost for an indoor start, with planting out 3 weeks after it, and this page simply resolves those offsets against the frost date computed for Peterhof.
The median frost-free season here is 167 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Can I grow melons in Peterhof?
The calendar estimates a planting window, not a guarantee of success. August is the wettest month in the rainfall grid, averaging about 90 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
Why is there no model planting window for melons in Peterhof?
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.
