October Temperatures and Light levels!

Here we go with new a graph!

Temperature Trend (Blue Line)

The daily mean temperature starts around 30.4°C at the beginning of October with a gradual decrease through the first half of the month, stabilizing around 29°C after mid-October. Toward the end of October, temperature shows a slight recovery but remains below early-month values.

The lowest temprature registred is on the 22nd with 28,2°C.

Overall, the temperature variation is moderate, fluctuating within about 2°C, suggesting a relatively stable microclimate with minor cooling through the month, but is a good news for the coral that in this way they can breathe a bit.

Light Intensity Trend (Orange Line)

Daily mean lux shows much greater variability compared to temperature. The peaks of around 3000 lux are seen early (around Oct 6–8) and again late in the month (around Oct 26–28).

A sharp decline in light levels occurs around Oct 10–15, dropping below 1000 lux. In fact, we had a couple of weeks of rain and very cloudy sky .

From mid- to late October, light levels gradually recover but continue to fluctuate strongly.

Relationship Between Temperature and Light

The two variables appear to co-vary loosely: when light intensity drops sharply (e.g., mid-October), temperature also tends to dip slightly, suggesting that cloud cover or weather changes affect both. However, temperature is less sensitive to these changes than light, likely due to thermal inertia of the environment or shading effects in the nursery.
