About this calculation
America/Sao_Paulo · midnight to midnight: 10 Sept 2026, 00:00 → 17 Sept 2026, 00:00.
Both temperature limits are included. Each reading is assumed to hold until the next observation; time before the first and after the last reading is not estimated.
168 of 168 hours covered. Coverage measures duration under this assumption. Long gaps can overstate sampling completeness; coverage does not guarantee sensor accuracy.
Complete means the full period is covered under this duration model.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. Both displayed dates are included.
Each day uses the average of its observed high and low, minus the 10°C base. Negative results count as zero. The base is a calculation setting, not a recommendation for a particular crop.
7 of 7 days complete. Coverage measures how many expected 5-minute intervals contain a valid temperature reading. Extra readings in one interval cannot fill gaps elsewhere.
Complete means every expected interval has a valid reading. Observed highs and lows may miss extremes between readings; coverage does not guarantee sensor accuracy.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. Both displayed dates are included.
Each day uses the average of its observed high and low, compared against the 65°F (18.3°C) base. Relative demand is the daily deficit versus that base, summed across days. Negative results count as zero. This is an indicator of relative heating demand, not an estimate of building energy consumption.

Complete means every expected interval has a valid reading. Coverage does not guarantee sensor accuracy.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. Both displayed dates are included.
Each day uses the average of its observed high and low, compared against the 65°F (18.3°C) base. Relative demand is the daily surplus above that base, summed across days. Negative results count as zero. This is an indicator of relative cooling demand, not an estimate of building energy consumption.
7 of 7 days complete. Coverage measures how many expected 5-minute intervals contain a valid temperature reading. Extra readings in one interval cannot fill gaps elsewhere.
Complete means every expected interval has a valid reading. Coverage does not guarantee sensor accuracy.

276 of 288 five-minute intervals have an estimate. Incomplete history. Missing readings may conceal the actual maximum. Chart gaps are not zero WBGT.
About this calculation
Liljegren heat-transfer model, with FAO-56 wind-height adjustment when needed. Outdoor exposure; no universal risk classification.
Window: Sep 16, 2026, 13:21 → Sep 17, 2026, 13:21 · America/Sao_Paulo. Lines break at unavailable readings and gaps longer than ten minutes.
Latest inputs: air 23.7°C; humidity 56.0%; wind 0.8 m/s at 8.0 m; solar radiation 147.6 W/m²; station pressure 1,026.1 hPa.
Model inputs after adjustments: wind 0.6 m/s; solar radiation 147.6 W/m².
Weather sampled at observation timestamp; no averaging-period shift.
Reference globe/wick and surface properties; ground temperature equals air temperature.
Wind adjusted to 2 m using FAO-56 Eq. 47: neutral profile over short grass; actual terrain may differ.
Wind conversion assumes open short-grass exposure and a neutral wind profile. Roofs, trees and nearby buildings can make that assumption inaccurate. Station siting, sensor height and sensor quality affect accuracy.
Modeled from weather-station measurements, not a direct globe-thermometer or natural wet-bulb measurement. Personal exposure can differ.

About this summary
This summary covers the previous completed day in your station's timezone.
Complete means all five displayed metrics have sufficient data. Incomplete or unavailable data may make the summary Provisional or Missing.
Missing values are never treated as zero.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. The view covers the previous 30 completed days, showing the available date range.
2026-08-18 → 2026-09-16, both dates included. Chart scale: 0–284.4 GDD.
Base temperature: 10°C.
Daily warmth is summarized from the observed daily temperature relationship across the configured base. Negative daily outcomes are counted as zero. The line adds these daily values within the displayed range.
Coverage measures the proportion of expected 5-minute intervals with valid temperature readings across the displayed days. Extra readings in one interval cannot fill another. It describes the available daily records, which may not yet include recently received readings; it does not guarantee sensor accuracy.
Provisional: 1 incomplete days, including 0 missing. Incomplete days contribute without scaling. Missing days do not count as zero warmth.
Complete means every expected interval has a valid reading. Observed highs and lows may miss extremes between readings.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. 2026-08-18 → 2026-09-16, both dates included: the previous 30 completed days.
High and Low are the highest and lowest temperatures observed each day. Incomplete days use the available observations. Missing temperatures are never filled or treated as zero.
Chart scale: 10.0–33.3°C.
Coverage shows how much of the 30-day period has temperature readings. Complete means all expected readings are covered; otherwise, the period is Provisional. Recent readings may take time to appear.
Provisional: 1 incomplete days, including 0 days with missing temperatures.
Temperatures may rise above the observed High or fall below the observed Low between readings. Coverage does not guarantee sensor accuracy.

About this calculation
Days run midnight to midnight in America/Sao_Paulo. 2026-08-18 → 2026-09-16, both included: the previous 30 completed days.
Each day uses the saved maximum of the station’s cumulative daily rain counter. A detected decrease makes that day provisional because a reset cannot be distinguished from a correction.
The total sums available daily values, including provisional observations, without scaling or interpolating missing rainfall. Zero means valid observations with no measured rain. Missing rain remains unknown.
Coverage counts expected five-minute intervals with valid rain readings, independently of temperature. Complete requires full coverage, a summary read after day end, and no detected counter decrease. Coverage does not guarantee sensor accuracy or capture rain after the final sample.
29 of 30 days complete; 0 days missing. The period and its observed total are Provisional. Recent readings may take time to appear.
What do these indicators mean?
Chill Hours · time in the cold
Some perennial plants need a period of cool weather during dormancy. Chill Hours estimates time in a chosen temperature range. This seven-day view shows recent cold exposure, not a full season or whether a plant’s needs are met.
GDD · warmth over time
Growing Degree Days describes heat accumulation that can help track biological development. Each day uses the average of its observed high and low, above the base temperature. The 10°C base is an initial setting; different organisms have different needs.
HDD · relative heating demand
Heating Degree Days are an indicator of relative heating demand relative to the 65°F (18.3°C) base; they do not model or infer actual energy consumption. High values mean more heating demand inferred from the daily mean temperature relationship.
CDD · relative cooling demand
Cooling Degree Days are an indicator of relative cooling demand relative to the 65°F (18.3°C) base; they do not model or infer actual energy consumption. High values mean more cooling demand inferred from the daily mean temperature relationship.
Based on station temperature readings. Coverage describes the available evidence, not sensor accuracy. Reload to recalculate the latest period.
