Temperature-based estimate. Matadi 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 March (about 167 mm), and the driest is July (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.

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.

For basil, also check drainage, sunlight and cultivar requirements. See the rainfall context above; humidity, irrigation and local pest pressure are not calculated.

Local growing check

Before choosing basil for Matadi

  • March is the wettest month in the rainfall grid, averaging about 167 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 basil

Use the calendar to plan ahead, then check the conditions in your own garden.

  • Measure the soil at sowing depth. Aim for at least 18°C (64.4°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.

Keep basil leafy with warmth and regular tip picking

Start with healthy plants and a sunny, drained position. Keep moisture available without leaving the roots waterlogged; yellowing leaves are a reason to inspect roots and leaf undersides before adding fertiliser.

Pinch growing tips above a pair of leaves to encourage branching, and remove flower buds if leaf production is the aim. Where downy mildew has been a problem, look for a cultivar with documented resistance and leave space for airflow.

What to record this season

Which cultivar stayed leafy longest, and when did flowering or leaf disease begin? 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. Matadi 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 basil between 18°C (64.4°F) and 32°C (89.6°F) — and in Matadi every monthly mean falls inside that range, which is why the headline says "year-round warmth". Monthly averages can hide unsuitable hot spells. This temperature result does not establish a year-round planting recommendation: check rainfall, drainage, day length and cultivar requirements.

Growing basil in Matadi

Can I grow basil in Matadi?

The calendar estimates a planting window, not a guarantee of success. March is the wettest month in the rainfall grid, averaging about 167 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 basil in Matadi?

Matadi has no dependable frost season, and monthly averages fit the temperature model for basil all year. This is not a year-round recommendation: check rainfall, heatwaves, day length and cultivar needs. The crop maturity guide is 50 to 70 days under suitable conditions.

How much frost will basil 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.
