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 Narva
August has the highest average precipitation (92 mm); March has the lowest (47 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 runner beans for Narva
- August is the wettest month in the rainfall grid, averaging about 92 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 runner beans
Use the calendar to plan ahead, then check the conditions in your own garden.
- Measure the soil at sowing depth. Aim for at least 12°C (53.6°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.
Put the climbing structure in place before sowing
Install a strong frame before the roots and stems spread. Place plants where the frame will not shade shorter crops and where you can reach both sides for picking.
Keep water available as flowers and pods develop, especially in dry weather. Poor pod set can reflect conditions around flowering; it is not automatically a reason to add more fertiliser.
Pick pods young and often before they become fibrous. Letting many pods develop mature seeds changes the plant's priorities and reduces the value of a tender-pod harvest.
Growing in a container
Use a generous, stable container with a firmly anchored climbing frame, or choose a dwarf variety. Tall beans and light pots are a poor match for an exposed balcony.

Why these dates
Install a strong frame before the roots and stems spread. Place plants where the frame will not shade shorter crops and where you can reach both sides for picking.
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. Runner beans are timed from 2 weeks before that frost for an indoor start, with planting out 1 weeks after it, and this page simply resolves those offsets against the frost date computed for Narva.
The calendar also applies a soil-warming estimate derived from historical air temperatures. Where that estimate is later than the frost-based date, it delays the window. Soil in your own garden can warm earlier or later; a thermometer at sowing depth is a better final check. Cold, wet conditions can slow germination and increase decay risk.
The median frost-free season here is 186 days, against 60 to 80 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing runner beans in Narva
Can I grow runner beans in Narva?
The calendar estimates a planting window, not a guarantee of success. August is the wettest month in the rainfall grid, averaging about 92 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.
When should I plant runner beans in Narva?
Aim for 25 May - 8 Jun in an average year. If you would rather not gamble on the weather, wait until 25 May - 8 Jun - by then frost has finished in nine years out of ten.
Can I plant runner beans earlier in Narva?
The historical frost estimate is 3 May. For Runner beans, an air-temperature model estimates soil warmth of about 12°C (53.6°F) around 25 May. This is not a soil measurement or a forecast. Check your bed at sowing depth; cold, wet conditions can slow growth and increase decay risk.
When might runner beans be ready to harvest in Narva?
The estimated period is 24 Jul - 13 Aug, based on 60 to 80 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 runner beans 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.
